Remote control freeze's up

Remote control freeze's up

When connected to another PC, and trying to disconnect it freezes up and it locks up any open IE window on my PC.  Only thing i can do is to use Task Manager to kill the IE session and even that sometimes doesn't work.  So I have to restart my PC.  This sometimes happens 2-3 times a day.
This has started to happen in last 2 months only.
