I was going to listen in on an accessibility and universal design in teaching session.
My wireless mouse stopped responding on my desktop - turned everything off and on a few times - looks like the batteries are ok - pulled out the USB receiver - put it back - nothing. Little tiny wireless mouse I use sometimes on my laptop isn't working on the desktop either. I had this happen once before - and I can't remember if I actually DID something or it just decided to work again. My laptop with its wireless access does not seem to be enjoying the Blackboard Collaborate experience at all this afternoon... I think it's time to take a break.
