Scratch fails when opening projects
hi everyone,
With version 1.3, I am having really a lot of trouble with opening projects.
I am having this problem with, for example, every Raytracer Canthiar ever made.
This problem only occurs to some files. Others work perfectly.
When I click Open and browse for the file, it shows up. I click it (to select it) and the thumbnail is a black box. When I click open, the "Reading..." bar appears, it fills up, and when it disappears the Scratch application locks up. I cannot click any buttons anymore etc.
Windows does not reports the aplication as "Not responding" and when I click the clos button, a dialog box appears saying "Do you want to quit Scratch?" and when I hit yes it closes - as usual.
I am having this problem with really a lot of files, however none of the ones I made myself.
Can someone, maybe a Scratch Team member please help me?
I am investigating this problem and I will post some screenshots soon.

Re: Scratch fails when opening projects
Never had this problem personally. Are they in the same version when you open them. For example are you opening a Version 1.3 project in Version 1.2 scratch or something like that.
Other than that, I don't know. Sorry =\

Re: Scratch fails when opening projects
I have not seen this problem either. I was able to successfully download and open this ray trace project of Cathiar's
http://scratch.mit.edu/projects/Canthiar/56074
using version 1.3. Sorry, no idea what is going on with you. Have you tried a fresh installation of Scratch?

Re: Scratch fails when opening projects
Maybe the problem is related to just that particular machine...
I am trying on another computer right now and it works fine.
I don't think it has to do with my version of Scratch, Jens' "BYOB" failed too - it is another, undamaged image file.
I wonder what the real problem is...

Re: Scratch fails when opening projects
Hi Joren,
I'm sometimes experiencing something similar when I use a computer running Windows XP and Firefox3. Whenever I download something from Firefox3 under XP to directly open it in Scratch it tells me that it can't open or even find the project. I have been chasing this weird bug but not been able to find a plausible explanation for it. My current hypothesis is that maybe it's a Firefox3/XP character encoding bug, because Scratch will open these downloaded projects using either the command line (double click), drag and drop, or its own file open dialog box. So could you tell some details about the environment you're using? Oh, and there's another observation: Sometimes systems get mixed up by accented characters. This might also be worth a try to look at...

Re: Scratch fails when opening projects
Both computers I tried have XP Pro SP 2or3, Firefox 3
On the first computer I have the problem listed in the first post. Scratch 1.3 fails to load, Jens' BYOB image too. BYOB returns an error message ("Could not read; FIle may be damaged; (bad header)" ), Scratch 1.3 does not - it locks up.
On the second computer, Scratch 1.3 (using Scratch.image) succeeds to load all projects, including the examples I listed above. (Canthiar's raytracers). The BYOB
image fails, again returning "Could not read; File may be damaged; (bad header)".
I tried downloading the file with Internet Explorer 6 and 7, Firefox 3 and the problem remains...
It does not seems to be related to Firefox 3. Maybe it is related to damaged image files - maybe the BYOB image is damaged...
Another thing is that on the first computer, scratch projects are automatically opened with Scratch, but they have a "unknown ffile type icon". Firefox opens Scratch Files with Scratch, but calls them "Word documents" I think I better reinstall Scratch...

Re: Scratch fails when opening projects
Well, it's no wonder that you cannot open Scratch Projects in BYOB, because I didn't bother to make it "backward" compatible with Scratch. So that "bad-header" notification is to be expected.
So, basically you have the problem only on your first computer. Maybe you should check your hard drive for defects...

Thanks. That clears out a lot.
