I'm not a Windows/MS Visual Studio developer, but there has to be a way
to profile an application -- find out where in the code it is spending
all that time.  If it turns out the time is being spent in the Qt
library, then the library probably has an issue... if in underlying
Windows API calls, then that's where to look... and so forth.

A quick Google suggests the tool you want is called "Visual Studio
Profiler" and that it is part of Visual Studio 2008.  See

about it.

Hoping this helps,
