qt ver. 3, linux, windows, and modal forms

Hi,

I'm having a problem with modal forms on windows. I've written a very 
short test program, with a main window and a form called from the main 
window. The form is set to modal with form.setModal(1) before calling 
form.show().

All works as expected on Linux. The form is modal, not allowing the main 
window to received the focus. If I call the form from within itself, the 
topmost form is modal, and not of the previous forms will receive the 
focus until the topmost form is closed; then the next topmost is modal, 
and so on.

However, on Windows XP Pro (at work - don't use windows at home), the 
form is not modal. The main window will receive the focus with a mouse 
click even though the modal form is still on top.

The source code is identical on both OS's.

Has anyone run into this before? Is there a fix? I haven't been able to 
find anything with google searches, and Trolltech's forums don't seem to 
have any entries addressing the problem, either.

I have a progam that I'm writing for work using Qt and Python, which was 
like pulling teeth with our Microsoft oriented IT department, and I very 
much do not want to tell them that it's not going to work (modal forms 
are essential).

Thanks for your help,
Mike
