I ran into the same thing yesterday under WIndows 98.  I was able to 
use it by going back my V3.4 VM.

Not sure what the problem is.  I decided to go back and finish my 
project on the Mac.  Actually this surprised me.  It's the first time I 
can remember a fresh Squeak final release not installing or operating 
correctly.  I just assumed it was something I did wrong.
