Qt is so clear lib, so there's no reason to suspect Qt-4.3 for such  
things, but you're right it could be problem - at least until 4.3.1 ;)
Most problems (which I don't understand really) comes from LCL, with  
same code, heaptrc says that I have mem leaks (at home), but not at my  
devel machine at work.
TStatusBar isn't visible on any of those machines (XOrg-6.8.2), but on  
my laptop (XOrg-7.0), but it's also not visible in clean install of  
FC7 (XOrg-7.2) (inside vmware) ?!?

I'm just wondering why your demo binary works as expected on my  
machines , but after
recompiling your source I get totally different results.
