Actually I didn't specify any parent at all:

class MyDialog(Dialog):
    def __init__(self, title=None, tmpl=None):
        self.title = title
        if tmpl is None:
            tmpl = dlg_template()
        Dialog.__init__(self, tmpl)

I don't see the parent being passed into the dialogs in pywin32's
sample code. Is this going to be a problem?
