Hi folks,

in the "Scripting with Squeak" Seminar we're giving, Markus and I have 
encountered a problem with Projects becoming difficult to save because 
of memory issues.

A little snooping revealed that the problem was with 
Morphs/Etoys/Players that were being animated by changing their costume 
using scripting tiles (the  "... look like Holder's playerAtCursor / 
increment Holder's cursor" pattern).  These seem to accumulate all the 
customes they've ever had in the "costumes" instance variable of their 
"player".

Since our students tend to leave their animations running in the 
background while they work on other stuff, that adds up to a LOT of 
customes.

Is this the intended behavior?  Can I turn it off somewhere?

I have a small snippet of code to zap all of these costumes.  Is this 
safe or will I destroy something important?

Thanks,

Marcel
