I was trying to run test cases for a project I'm working on, when I  
started getting a lot of errors (Unwind errors, or something like  
that). I eventually got them to stop, but a few seconds later the  
entire squeak environment went black. I had to force quit (working on  
a mac here), and when I tried to restart squeak, it appears to load,  
but nothing shows up.

Is there any way to recover from something like this, or will I need  
to go back to a fresh image? I have a fair bit of code already  
written, and I'd rather not lose it.

I've had intermittent trouble with squeak locking up (usually as a  
result of something I've done--but sometimes command-. doesn't fix  
things and I have to force quit). Are there any steps I can take to  
make squeak more stable?

Thanks,
