wireless desktop problems

My keyboard and mouse are now playing up. They were fine for a couple of
days after installing VISTA.

I have a Microsoft Wireless Comfort Keyboard and the accompanying optical
mouse.

Problems include mouse freezing

Mouse not going where I am trying to point it

Keyboard repeating a letter even if the letter has been lightly touched and
by this I mean
rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrr

Keyboard not printing a pressed letter

Backspace deleting 2 -3 lines of text when only pressed long enough to take
out one or two letters.



I have been into the settings and altered them to the lowest repeat etc

I have also been into the drivers to update them but they report back as up
to date

And I have pressed the reset buttons so many times it feels like it's after
every letter. This is an intermitent problem, in that it might be fine for a
while and then jsut decide to go whacky. Time ranging from PC switching on to
having been on a couple of hours.

Any ideas or similar problems? BTW I have just moved the reciever to see
if that helps. I have also been on MS site to look for drivers but it
doesn't give a UK English language option just a US one
