FVWM: Bindings and/or mouse clicks going wonky

Hi all,

I've done a new Gentoo install, and put FVWM on it.  Started putting a
config on it and using it.  It worked fine for a little while, but
after a while, my menu seems to have reverted back to the system
default menu.  If I open a console and tell it to re-read my menu
config, it doesn't throw any errors, but the menu doesn't change,
either.  Also, while this is happening, my title bar bindings stop
working.  The buttons are still there, but clicking them does nothing.

While looking into it, I came across the FvwmDebug module, but when I
load that up, nothing gets output to the console, and if I try to
output to a file, no file gets created.

I'm not sure where to continue troubleshooting this one.  If the
bindings were disappearing or getting overwrtten somehow, I'd expect
the title bar buttons to go away, and the root window menu binding to
just stop working, not show the default/system menu.  Does anyone know
why this might be happening, or be able to offer guidance on where to
look for signs of trouble?
