Problem - SP3/activesync?

[Guest]

When I'm at the desk, I've always just left my SP3 plugged in via the USB cable, with activesync set to update as soon as changes are made.

Doing this, I've never had any problems, or noticed the computer slowing down.

Recently however, the computer does seem to run slower when it the phone's plugged in.

I could be imagining this, or it could be something else on the computer causing the problem, but I just wondered if anyone else has had the same problem??

TIA

Pete.
