I wouldn't be very surprised if this turned out to be a threads- 
related bug.

The AppKit is generally not thread-safe, so if an NSSavePanel or  
NSOpenPanel is run from another thread (e.g., by typing forms in a  
Listener window), I can imagine that something could get botched if  
those panels try to update the defaults from multiple threads.

I did add a couple of dialog functions to the trunk recently.  They're  
at ccl:cocoa-ide;file-dialogs.lisp, and they're careful to run the  
panels on the event thread.  The Easy GUI functions should probably  
call those.
