Check the Glossary; it has instructions on how to make a cap. 

Where's the glossary?

When I select save image for end-user it brings up a black, uncloseable screen and does not save a thing!    help? please?

Hmmm never has happened to me... idk what to do...

I do.

techdoodle, click twice on the black. Shift click the R again, and choose "Turn fill screen on". Try saving the image now.

I clicked twice and nothing hapened....

Are you holding down shift?  And make sure it's the curvy part of the R...

He's talking about double-clicking on the black. He can't get back to shift-clicking the R again because it isn't there

Speaking of the glossary, by the way, I came across some wonderfully easy to grasp explanations for some of those features found so often in Squeak and other OOPs at a lecture I had yesterday:
Objects

• Objects have properties, methods and events
• An object is based on a class
     – Objects (noun or thing)
         • Forms, Controls
     – Properties (adjectives)
          • Name, Color, Size, Location
     – Methods (verbs)
          • Close, Show, Clear
     – Events (occurs when user takes action)
          • Click, KeyPress, Scroll, Close window
     – Classes (template or blueprint)
          • Contain definition of all available properties, methods and
events

I'll update the glossary with these if people like them later when I have a moment

Replace the whiles with t1\\12 (t2 mod 12) which returns the remainder of t2/12. If t1 is huge, Squeak will temporarily freeze. Oh, and you may want to replace t2_t1 abs with t2_t1 abs rounded (just in case) and t1 ifNaN: [^self]. (again, just in case).

Good ideas!  I'll add t1 isInf too.

Also for panther, I'm officially requesting a "Delete background $Number$" and a "Delete costume $Number$" block to go with it. Also is there an import image from file block yet? (weebly blocked so cant check easily)

A dropdown for two values?  Really?

Yes!! Much better then all these extra blocks.

BYOB blocks:
Forever when % is true:


Forever when % is false:
