I did see this message when you posted it to the list, but I was
hoping that someone would say "yes, I've seen that" because I haven't.
And debugging problems that I can't reproduce is obviously difficult
(and I have a few of those queued up too).

What version of 2.xx exactly?  'fvwm2 -version' will tell you.  Also,
what OS are you running under?

Well, now that I think about it I seem to recall some discussion about
something like this in the past...  Hmm...

Ok, a quick search of the fvwm mailing list archives (found on the
official web site - a handy thing indeed) for "pager;X_SetInputFocus"
reveals a note & subsequent threads about this in the past (under
Solaris 2.x).  The original poster claimed that an included patch to
x_pager.c in the FvwmPager directory worked for them, but I didn't
really like the solution at the time, which apparently is why I didn't
include it then.

So, try this patch:

I seem to recall not really liking that fix, but give it a try and see
how it works for you.  If it seems to fix things for you, let me know.
I'm putting it into the next release anyways (it really shouldn't hurt
anything, I guess, even if it's not an elegant solution).

Yeah, it's pretty tough sometimes.

That's correct - I don't see this (but then I normally only use one
desk and I rarely drag windows out of the pager like that, but trying
to reproduce it just now I was unsuccessful).

Ugh.  Well, I hope this works so you can give them a good demo of
fvwm.  I think (hope) that for the most part they'll like fvwm better.
Also, take a look at the Red Hat under the desktop contest winners
section - someone made fvwm2 look an awful lot like the COSE desktop
using some special pixmaps and the FvwmButtons module...

Hope I've been of assistance.
