No, I am not aware of that bug! Unfortunately, I can't reproduce
it here on my machine and I can't remember to have had a problem
with LightButtons. The entry on the VMD web page is quite old
(from 2000). Are you sure you're really using a new (1.0.91 or
newer) version and you're program isn't picking up an older
version of the library accidentally? (It should be easy to check:
just click somewhere within some window with the middle button
while pressing the <Alt> key - then a box with information about
the version should pop up.) If it's a newer version could you
perhaps send me an example program that exhibits the bug? That
would be very helpful!
                         Thanks and best regards, Jens
