Serious bug with X forwarding?

The vnc.so module in our binary distributions is built against XFree86
4.2.1 and works absolutely fine for us.
I'm surprised that there is any difference according to which viewer is
used - it really shouldn't matter. What happens if you use vncconfig
-disconnect from within the desktop rather than killing the connection
from the viewer end? Can you try this with both Linux and Windows viewers.
One thing you could try is to build vnc.so from source using XFree86
4.3.0 - it could be there's an incompatibility with 4.2.1.
