I have an interesting glitch (at least I think it's a glitch) involving a gravity script in a game I made. (http://scratch.mit.edu/projects/ZorchyGroxFox/2885411)
In the game, your ship is placed in orbit of a black hole and must collect targets whilst dealing with the strong gravitational field. The glitch (if indeed it is one) causes your ship to be instantly teleported to the center of the black hole if it touches the corners of the stage. I tried disconnecting a few scripts (including the black hole death script, which left you alive but immobile) and finally found the glitch absent when I disconnected the gravity script. However, I could find nothing wrong with the script, at least nothing that would cause what I was experiencing. Furthermore, I found no such problem when I played the project in the web player; it seems only to happen in Scratch when downloaded.
I'd appreciate it if someone could download the project and find out if the glitch happens whenever the project is downloaded or only on my computer.
Thanks in advance.

Downloaded the game and tested it and your game does have the glitch.

This happens sometimes
When you talk to professor Oak, after battling the trainer, you run up to him, stand on his head and then start talking! Only a small glitch, but hey, a glitch is a glitch.

Huh. Thanks for testing it; I'll check back over the scripts one more time, just to make sure it's nothing I did.
Did you happen to play it on the web player too, if so, did you get the glitch there?

Ah, I think I found the problem (unsurprisingly, it's a mistake I made rather than a glitch of Scratch itself; I guess it has something to do with the fact that the Flash player doesn't stop scripts when they try to divide by zero.
Anyway, my gravity script had bits that involved the log of distance minus a constant, so if the ship got further away from the black hole than the magnitude of said constant (i. e. going into the corners of the stage), it would make the program try to take the log of a negative number, which killed the script. (I tried to put this in scratchblocks, but I got tired of proofreading all the nested parentheses. If you really want me to, maybe I'll try again...)
Anyway, fixing it was really simple, I just had to add a few to that constant. This is what I get for Scratching after 11 pm, I suppose... >.<
Sorry about that, I'll try to go over my own projects more before I come here to complain about glitches.

Well, thanks for the report...and I'm not sure if we shouldn't classify that as a bug anyway.  The Flash player is supposed to run Scratch Projects as similarly to Scratch 1.4 as possible (with a few exceptions where we decided that Scratch1.4 was in the wrong - like stamping a sprite that has ghost effect).  But we've never really made much of a fuss over the fact that Scratch 1.4 and the online players handle division by zero differently.  I think I'll at least bring it to the attention of the development team and see if it's something we can or should try and tackle.

When I was trying to make a music video, this rectangle showed up at the back of the guy who was dancing in the music video (Whenever you click the flag it happens a lot).
So I was wondering how I could fix it. Here's the link if you have any suggestions. http://scratch.mit.edu/projects/EpicStickGuy_TEST/2901050 

Sorry, I'm not seeing any difference between what shows up when I run it downloaded and what I see in Flash?  How about you - do you see different behavior when you run it downloaded in Scratch 1.4?

Looks more like a custom block of some sort.  What does it do when you run it?

Thanks for the nice screenshot!  Is this happening on all projects that you run in your browser? 

Can you verify that you are running the latest version of Firefox?   To get the version number, try going to the "Firefox" tab and selecting Help->About.  That should give you the version number.  You might have to go to the Mozilla site to see what the latest version is though.

Game is completely broken. You'll see why when you start.

Yep, that's a bug.  It looks like the change size by value is being rounded - so trying to change by 0.5 sometimes rounds to zero.  Or maybe the size is being rounded after the change by amount is applied.  Either way, that's not how Scratch 1.4 does it so it's a bug.  I've added it to the bug list here.

Neither can I...it looks like the invisible sprite that is in front is blocking access to the text entry.  I've added it to the bug list.

Also, in this project, when you click a few times, then full screen it, the whirl is distorted. If you click again, it goes back to normal. Then try small screening it. The whirl is messed up. It looks pretty funny though, lol 

The music timing is off! And on many projects, some scripts wont happen, instead, one script just keeps repeating on and on and on, until a certain point!

My project is being affected greatly! The score stampers on my game, Toasty's Adventure!, are all messed up because of whatever new flash player update that just occurred! I know that it's a flash glitch, because I downloaded and everything is fine! I even tried changing the scripts with no luck in fixing it! The glitch is that the scores' ones, tens, hundredths, and thousandths places match at all times! For instance, if your score is 256, it will read "222" until you reach 300 points, at which point it will read "333"

PLEASE FIX THIS! This game has received lots of attention and I would like for people to continue posting their scores and being excited when they play!

Wow, interesting glitch! We could use help finding the exact reason. Can you post the scripts that handle the score updating here? This isn't something that anyone else has reported, so most likely it's special case related to the way you implemented score handling. We can fix it, but you can help by isolating the part that works differently on the flash player than it does in Scratch.

When I uploaded the game to the Scratch website, the variables that I display on the screen didn't stay where I placed them. Instead, they moved to the default position in the upper left corner of the screen. Gets in the way of the game! Could not figure out how to fix this one.

It doesn't play well on old computers

In my project Minecraft 0.7 the blocks are moving I don't add that feature I wad using Google chrome and I got fast internet. 

when gf clicked
repeat until <(online) > [true]>
  go to [mouse-pointer v]
end
think [this is a bug] for (3) secs
