In my case it happens with KDE.

This means that most modern linux desktops expose the problem.
While going back to fvwm2 may have been a solution to you,
I doubt that this can be the way to go for many others.

But as long as we don't have a better analysis of where
the problem originates, any workaround helps. What somehow
surprises me is the fact that Pmw 0.8.0 worked fine, while
0.8.4 has the problem (didn't test the intermediate versions).
I don't currently have the knowledge to figure out if my
proposed modification really "solves" anything, but at least
it makes the symptoms go away. Any further enlightement
would be higly welcome!
