When I vnc in to my mini running 10.6.4, I frequently get keyboard hangs. Either the keyboard stops working altogether or just the shift stops working. Sometimes the keyboard acts as if I am pressing the command key when I'm not. This happens regardless of the vnc viewer and never when I vnc into windows, only osx. It also happens regardless if I use vine server or the built-in vnc server via screen sharing. Any thoughts? EDIT: it happens mostly in Numbers.
