As a Windows 7 (64-bit) user since March, I can say that on Windows 7 I 
have experienced a much higher rate of push-the-button crashes than on 
the prior XP.  Most of them seem to be related to threading, Firefox, 
and Flash, but after installing FlashBlocker, the rate of crashes 
decreased, but didn't go to zero.  There are a few that do not correlate 
with Firefox.  The reason I include threading in the mix, is that my 
style of Firefox use is to have many tabs open concurrently, and I think 
Firefox launches a thread (or maybe more) for each tab.

I have been extremely disappointed with Windows 7 because of these 
crashes, my usual technique of reading Web sites while waiting for other 
work to happen is made impossible, because the other work will get 
crashed too, since Windows reboots the machine instead of just 
terminating a process.

I'd be glad for any explanations of why it does that, although it is 
straying off topic for this newsgroup.  But mentioning my experience 
with Windows 7, seems relevant to the question above: it may not be an 
application problem, nor a Qt problem, nor a PyQt problem, but a Windows 
7 problem that makes crashes more frequent and more severe on Windows 7 
than on other platforms.
