Sorry I haven't got an answer Mike, but here's a few things you might 
like to check, in some sort of order (and in the hope it isn't telling 
you how to suck eggs):

-  Is Windows running at normal speeds?

-  Is the hard disc activity much more than usual?

-  If you press the dreaded <Ctrl-Alt-Delete>, click on the 
<Processes> tab, then click on the <CPU> tab (repeat if necessary) 
until the top line reads System Idle Process, is the reading in the 
high-nineties? (97-99%-ish.)

-  If not, what other process(es) are eating into the ooomph? 
(Technical phrase.)

-  With VirtualRPC in a window, click on Tools-Options and select the 
<General> tab. Does the processor speed readout match your computer 
processor? If not, select <Manual> and enter the speed manually. Any 
better?

-  Do you normally run VirtualRPC in a window? If yes, select 
full-screen mode. Any better?

-  Do you have a back-up *default* installation of VirtualRPC on the 
hard disc? If so, close down the normal VirtualRPC, start up the 
back-up copy and see if it's any better.

-  If not, you might like to install a fresh, default copy of 
VirtualRPC *somewhere else on the hard disc*. To do that, start the 
normal installation process from the master disc. When you get to the 
page saying "VirtualRPC-xxx's files will be installed in the following 
directory:", change the default installation address (C:\Program 
Files\VirtualAcorn\VirtualRPC-xxx) to something else, of your 
choosing, e.g "C:\Program Files\VirtualAcorn\Back-up", and continue.

-  Once done, close down your normal copy of VirtualRPC, then 
double-click on the *new* VirtualRPC icon on the Windows iconbar to 
start it. Check that it does indeed give you a paint-fresh, default 
copy.

-  Any performance improvement?

HTH, regards
