I installed Qt Creator on my iBook (512MB RAM, 1.33GHz G4 processor, 
last release of Tiger) I don't remember exactly which version of Qt is 
installed as my development version (it's definitely 4.4.1 or higher).

I'm observing the same issue with dropped keystrokes, although 
(presumedly because it's a faster system) not QUITE as many keystrokes 
are being dropped ("QuestionListWindow" invariably comes out 
"QuestionListWin" or "QuestionListWind" if I'm typing at full speed).

Definitely looks like it could be an issue.
