I want to say I love this dock too but I am having a similar issue. When I undock my Windows 7 x64 system to go to a meeting the dock locks up or crashes however you want to put it. I can log off and log back on which fixes it but it is getting old to have to do so every time. I can shut the dock down manually and start it back up and everything is fine but if I forget and undock without shutting the dock down it locks up the dock and I have to log off and back on. Any ideas?
