better use "MyInfoWindow::MyInfoWindow(QWidget* parent,const char* name) : 
QDialog(parent,name,TRUE)

No, normaly not.

0 for the parent pointer means Toplevelwidget as far as I know, so it will be 
a child of the root desktop window.
0 for the name is just empty or not set.

I think you should try to make "infoz" a child of your Mainwindow (infoz = 
new MyInfoWindow(this);), but I think your code should work so far. 

If you or someone else can't fix this problem over the next 2 days, you could 
 send your program (incl. the makefiles) to my email-address . I will be back 
on sunday and will look over it. Interesting task. :-)
