Hi everyone,

I know this issue could be more close to Sratch area, I wonder if some 
of you with more experience on Squeak could give me a tip.

I'm having a trouble with Scratch on Gnome/Ubuntu 12.04 with squeak-vm 
4.10 in a PC model, Magalhaes Classmate.

After try exiting from presentation mode, Scratch hangs up, the windows 
is turned up white, and to may finish the application, we have to kill 
them from a console.

This trouble is happening only on this pc model i tried on another pc, 
and work fine.

Is there some way to enable the debug output to see what happens when 
did click on button to exit from presentation mode ?

Another suggestion to try find out the problem ?

Thanks in advance.
