Hi Darryl! Thanx for the quick response!

A)Yes I am using a QDialog, but not standard OK/Cancel Buttonset. But I also
tried this out. I tried the accepted/recected slots and the methods quit()
and close(). In every case it closes down the whole application instead of
only the dialog window. Theres also no error message, it regularly closes
the whole programm. That really sucks.

B)The setModal() function I also tried out but it does nothing. The
application I started the dialog from doens't care about. But as soon as I
try working in the application with my dialog opened it crashes.

Thats really bad, because like this, the dialog I've written for the last
two weeks is completely useless. :-(
