That's actually what happens - the dialog throws EVT_INIT_DIALOG
before it displays itself.  Not that I really agree with you.  I don't
think that a "do such-and-such dialog" appearing with a "Select file
for such-and-such" file selector on top of it, the file selector being
in focus, is confusing for the user.  Actually, I think it'd be
friendlier - the user can see where the data from the file is going,
so has an immediate reminder of what the (generic) file selector is
for.
