Well, you can check that with a fresh dialog. One you get from uic/designer 
with no implementation behind it..
I'm sure that object creation (like timers) is quite expensive in C++, so this 
might indeed slow things down..
There is enough free memory?
I mean, there are no disk-buffers being freed for this, which might slow down 
the initialisation?
