Sorry, wrong answer. Shuffling him off to some other newsgroup with a
rebuking reply implying that he should have gone there to begin with
is not correct. This problem isn't ipso facto a native-code-requiring
problem; without prior knowledge that it's not true, there's no reason
not to think that either an AWT (or whatever) method group exists to
query for factoids about the native windowing system's status, whose
return behavior would obviously depend on the applicability of that in
the particular environment encountered, or failing a standard library
class for this sort of thing a third-party one that does it.
