While I had some problems with earlier versions of mulitplicity, version 1.02 seemed to work good until about 5 months ago. The cursor will readily go from the primary screen (right screen) to the secondary screen (left screen) but after about 2 to 5 seconds the cursor moves back to the primary in the upper right hand corner. I have the alert box feature on to tell me what screen the keyboard and mouse are controlling. When I switch to the secondary machine it indicates that I'm controlling the secondary machine from the primary console. When the switch back to the primary occurs the alert box disappears as if I had switched manuall. There is virtually no traffic on the network. Ping times are less than 1 msec. I've tried using keyboard shortcuts instead of the mouse to the edge of the screen with the same results. I've seen some suggestions to turn off clipboard sharing. I'm not sure how to do this and I wouldn't want to do it except for trouble shooting as this is a valuable feature.
Any help will be appreciated.
