Clicking on the title bar of the window usually fixes this. Whether or
not windows exhibit this problem tends to depend on how they update their
display - if they don't use Windows messages then WinVNC can't catch the
updates. There are also some special "kludge" options in teh VNCHooks
section of teh registry, to help get round such apps.

Thsi bug has now been fixed in the up-and-coming revision of WinVNC.

It's hard to say. That depends on whether it becomes easier to trap
screen updates in future versions of Windows and on whether the
algorithms/encodings used by the VNC system improve.

Until the next release, using non-8bit displays on the Windows boxes will
fix the colour problem.
