I'm not trying to make anyone feel bad and being a software developer 
myself I know how frustrating it can be to get vague error reports..  I 
didn't mean to be vague, I was just curious if other people had experienced 
a similar problem.

To be more specific about my problem, I suspect that it has to do with the 
fact that I set my color depth to 32, coupled with a 1600x1200 
resolution.  If I run the 3.0 image and set my display depth to 32, the 
space left is 1,607,204.  I visited various things in the Worlds of 
Squeak.  In particular I went to Fun With Morphic and click on the keyboard 
a few times, went back to the previous project, played the Bach 
fugue.  Space left dropped to around 1.4 meg after all this.  I then opened 
a new Morphic project and entered it.  I set a gradient color.  I opened a 
file list and filed in a .st file (contents attached).  I then opened a 
workspace and executed this line:

x := PetesTurtle new.

which successfully placed a turtle on my desktop.  I then executed this:

x go: 200

which proceeded to display the Space Is Low window.  Once the window 
appeared, the system hung.

I realize that specifying a 32 bit large resolution window will consume 
large amounts of memory, but it doesn't seem that the system should 
hang.  It also seems that Squeak should start out with more memory 
allocated to it by default.  I know that I can specify more memory on the 
command line, but the first time Squeak user is more likely to run it in 
the default configuration and may be inclined to do the things that I 
did.  If the system hangs, the new user is more likely to think that Squeak 
is bad and not to think that maybe he just needs to allocate more memory to 
the VM.

I've also attached the low space debug log file.

I hope this is less vague.  :-)
