Hi Bob, I'll take a stab at this. Thanks for the feedback. There is a 
lot of history here and the situation is complex. One would almost have 
to answer that Squeak does not at this moment provide the kind of stable 
UI development platform you're looking for. But, you should investigate 
the BobsUI package that was just posted on this list, it has long been 
the nearest thing to a "standard" widgets library. And, investigate the 
Tweak project, which has a greatly cleaned up UI framework - *if* it's 
stable enough to base work a project on right now, perhaps others can 
say more about that.
