Stops working after switching monitors

Hi,

I had the trial version a looong time ago and it worked great.  I just bought the pro version 1.21 and installed it- not working at all.  I can connect from my primary (dell vostro 1700 laptop running vista ultimate 32) to my secondary (winxp home box) or other secondary (vista business box) with no problem.  The problem I have is that when I scroll to the second box (either of them) the cursor dissapears and the keyboard gets stuck on that monitor. Have to do a net stop command to get it back on my primary machine.  I think the cursor just scrolls to the bottom of the screen and will not move up or change screens- I seem to be able to move it left to right although I cannot see it.

I have tried changing my primary to both of my secondary boxes- I have disabled all firewalls (although I don't think that is the problem since I am able to connect).  I have removed the setpoint software from my boxes for Logitech but am still unable o use this.  I am using a two different bluetooth mice- a logitech dinova and a rocketfish- both have the same problem.  I have stopped all processes running I could and keep the machines running- same problem with both mice and all three computers.  I have even hooked up generic USB (belkin) and had the same problem.  I have tried leaving mice and keyboards connected to the secondary machines- and without them.

I have searched these forums to no avail- although some of the problems sound similar- none of the fixes has worked.  Any help would be appreciated!

Thanks,

Darion
