Bluetooth mouse problems

I'm not sure if i am posting this to the right newsgroup, so my apologies if
it in't right, but the problem is a bluetooth one.

I have been helping a friend who has just got a new Kensington Bluetooth
PilotMouse. I can install it on their system using a USB/Bluetooth dongle
and all goes beautifully until he shuts his machine does for a period of
time (30 minutes or more), and then when he starts his machine again, it no
longers sees the mouse. He then has to re-install the dongle software all
over again and do the discovery etc etc.

I have used both the dongle and the mouse on two other machines but I don't
experience the same problem. They both work fine on the other machines.

My conclusion is, and i would love to be right, but would be just as happy
for somebody to give me to correct solution, as the two machines that it
works on are running XP Professional, whereas the machine that it doesn't
work on is only running XP Home. that Professional has better bluetooth
capabilities. If so, is there something that i can install on my friends
machine to overcome this problem.

Thanks in advance for any help that you can offer (even if it is only to say
that you have had the same problem so that i don't think that i am going
completely mad!),
