File dialogs can be modal or modeless. That's been true since the very
first time I met them (which, admittedly, wasn't until the early 90s;
maybe someone remembers earlier and can tell me if they were
inherently modal 25+ years ago?), and there are good reasons for both
operation styles. Even if your dialog is modal, it's extremely common
to NOT block the application, but merely prevent interaction;
otherwise, your main window won't repaint, which is generally
considered to be a flaw. Rick, have you ever done any serious GUI
programming in anything other than Tkinter? Are you seriously unaware
of standard GUI widget functionality?
