[Qt-interest] Windows Aero effect with show() and hide()

[Nikos Chantziaras]

I noticed that when I hide() a window (QDialog in this case) and then 
show() it, Windows Aero will not do the effect it usually does when a 
window opens.  The effect only shows when I delete the QDialog and 
create it again.

Anyone else noticed this?  This is on Windows 7 x64.
