QWizard hides my QMainwindow instance upon showing and closes my app upon finishing o

[nvdstruis]

I create a QWizard instance in a QMainwindow instance and show it with show(). When it is showed my mainwindow disappeares. When I finish or cancel the wizard, the application is closed. I have been searching and trying various things but still haven't got a clue. Can somebody help me out here, this makes no sense?

The code looks like this:
void MainWindow::startMyWizard()
{

pWizard_ = new CMyWizard( this );//CMyWizard directly derived from QWizard
pWizard_->show();

}

This code doesn't do anything odd. Got a more elaborate example? Preferably a working one that we can compile and see what goes wrong.
