I found another thread abotu this by searching the term "virtual desktop"
in the Excel newsgroup, dated 3/29/05.
It appears others have noticed this problem (as have I) and there appears to
be no known fix. There is a workaround - minimize, switch, switch back,
de-minimize. Haven't tried it yet, but see the other thread I mention.
Incidentally they say that other Virt Desktop managers are preferable... I
tried the nVidia one that came with my gfx card, found that it was in some
ways preferable but in other ways not. Unfortunately my laptop doesn't
support it, and I would rather standardize for the benefit of minimizing my
required level of effort in adjusting from computer to computer. Therefore
I'm not using the nVidia one. I may try one of these aftermarket ones...
