You want to make it modal with respect to the current main-window only, but 
for that you need to pass a pointer to the main-window to NetAccess. We can 
move my modal-widget hack (or another hack) to KTMainWindow. I would propose 
a static function so that it will work both with and without parent widget.

Does my hack work if you use QWidget(0,0,WType_Modal) instead of QWidget(0)?

The semi-modal version would then read:

QWidget(parent, 0, WType_Modal)
