I had that problem in RHino, can't recall if I had it in Vue 6

In RHino, it's a bit of a pain to get rid of,, maybe worth a shot....

 

basiclaly, for the Rhino bug, the problem was with conflict with a "Pen tablet PC" set up, that Vista automaticlaly put in, wwhen I added my graphic tablet, not sure if it occurs without that.

go to PROGRAMS, UNINSTALL PROGRAMS
then TURN WINDOWS FEATURES ON OFF
then tick off the TABLET PC OPTIONAL COMPONENTS bit

takes a while to do it
when finished!! reboot PC, that should fix it :)
