No, I think it *is* likely. What I might have pointed out a bit more 
clearly, is that when I say "lots" of widgets, I don't mean 20 or 30 or 
even 100; I'm talking about literally thousands, or even tens of 
thousands of widgets. They are buttons, actually, displayed inside a 
scrolled window, with (to compound matters further) a couple of levels 
of boxes in between - there may be something like 1000 containers in 
additions to the buttons.

The actual number depends on input data, and with, say, 2-300 buttons, 
or perhaps even 2-3000, everything is OK, but with something like 20000, 
problems definitely occur. Like I said, the whole thing could use a 
redesign, but I was rather hoping I wouldn't have to do one right now, 
since I need to release a beta within the next few days (or preferably 
yesterday, as always.)

I didn't look at all, actually. One of my colleagues chose this package. 
I sort of assumed he downloaded the latest stable version for MinGW, but 
maybe he instead went for something closer to what we are using on Linux 
- where we always target the software for a somewhat older version so as 
not to force our customers to upgrade their computers every two weeks. 
(And I'm quite happy not doing that myself, too. Software doesn't rust...)
