Hi Dan, Thank you for your detailed comments. While the answer is disappointing, I understand and support the need for speed over trivial aesthetics. But a huge bunch of thanks for looking into this in so much detail!
I do wonder however, how something like pekwm handles this. It is pretty fast there (though I have not used it at the same intensity level as fvwm), but of course, does not have the full functionality of fvwm. So, perhaps not a fair comparison. Anyway thinking aloud, nothing more. Thanks again for your time and efforts!
