Umm, I didn't mean that VNC missed Win95 application updates.. I mean that
when I cover a part of the VNC window in X with, say, an xterm window, and
then click the xterm behind the VNC window, the part of the VNC window that
was covered by the xterm window remains grey. VNC knows what should be in
there (so it's not a problem with the win95 applications), but it doesn't
know that a part of the VNC window in X has been erased and should be
refreshed. VNC usually refreshes the whole VNC window contents when I first
click the VNC window back, then bring it in front of other windows again..
but I'd like it to refresh the window when I partly reveal the VNC window
from behind of other windows, too. Sorry for the bad explanation.. it's
because of a language barrier.. :)

Good :)

Good luck! VNC is pretty nice already.

Thanks for the reply,
