FVWM: EdgeScroll for fvwm on vnc

Hi folks,

for home office I am running fvwm 2.6.8 in a VNC session, using
the native resolution of my monitor at home. Fullscreen. EdgeScroll
is set to

	EdgeResistance          0
	EdgeScroll              100 100
	EdgeThickness           2

Problem: If the mouse hits (lets say) the right edge, then the
shown screen hops several virtual screens to the right, instead
of just a single screen, as known from fvwm on Xorg. The mouse
pointer is not warped to the left edge, either.

Is there a way to fix this? Any known workarounds?


Every helpful comment is highly appreciated.
