Yes, I had hoped that SP1 would fix mine, too, but it didn't.  Mine was
100% repeatable and even with SP2 I still had the problem.  A new driver
was released quite a while back, but the load failed with a message
saying it already had that version installed.  In fact, the version number
was slightly different by one letter.

The new driver was notified to me by the HP Health Check software, which
is set to check for relevant updates weekly.  Although this was only
notified last week, the new driver has a release date of 03/10/2009
version 8.16.11.8766.

It is now very noticeable that swapping between full screen and an RPC
window takes nearly 1 second now, and results in the windows menu bar
being drawn twice, one above another at the bottom of the windows screen
as it is redrawn, with a black screen above. That takes a quarter of that
one second. The RPC screen takes the further 3/4 second.  In fact, it
takes so long I can do a 'print screen' and capture it while its doing it.

In the other direction it is about the same at 1/2 second.

So I guess there is quite a bit of extra storage or recovery going on.
