Thought I’d let you know that slowing down the mouse appears to have
cleared the problem. My thanks to Miguel Monteiro for the solution and
all the other kind replies.
Now who knows how to resurrect a ceased to respond mouse (without a
reboot)?
Cheers

Hi Don, Dave,
Try this: go to
Start>Settings>Control Panel>Display>Settings>Advanced>Troubleshootingand move the “Hardware acceleration” slider down towards “None”. If the
problem goes away, repeat the process by moving the slider up one
position
each time, to find out the rightmost slider position allowing your mouse
driver
to work fine… (one position less than “Full” could work - it simply
disables
cursor and bitmap accelerations).If it works, don’t ask me why. I simply came up across a similar problem
a
few months back and found up this workaround… I think the problem
had
something to do with a cheap video card (might NOT be your case, of
course).Miguel Monteiro
