I can still see some problems, but I probably need to see over the next few days. When it started doing this it would kick me off my VPN connection so that can be one thing I can watch for.
Couple of questions if you don't mind:
Prevx is just a trial version.
AVG was also a trial version
The PC Security Shield is virus only; what else would you suggest I go with.
Also, have you ever heard of a mouse hanging on the Send to line? Or have any idea why it would?
