Thanks for that.

Yes, there is. Customer specification. "Modal dialog boxes: 1) will
not display titles in any taskbar. 2) Will not have either a maximise
or a minimise button."

It makes absolutely no sense whatsoever to have a minimise button on a
fixed size modal dialog box. None. It is illogical, and the fact that
the maximise button goes when fixed size is set supports that
argument. It makes even less sense when, say,  Message.Question() has
no minimise button yet I am prevented from choosing to have my own
windows look like that displayed by Message.Question().

So, how did you convince the window manager to not display the
minimise button for Message.Question()?
