Here's the problem:
I leave my laptop (Dell Latitude D600) on standby, then turn it back on later. After it's back on, Firefox won't work properly - I just get an 'unable to load page' message of some kind. This persists until I restart the computer.

It doesn't always happen, but it's often enough to be a nuisance.

Then when I restart, my mouse sometimes won't work until I unplug and then reinsert it.

Can anyone provide advice for solving these problems, or at least explaining why they happen? I'm using Windows XP Pro with Service Pack 2, if that's any help.

Thanks in advance
