Hi Folks -- I saw a post similar to this, and I guess I need some help I have a Microsoft trackball (PS2) attached to my belkin 4 port kvm -- the switch has 3 windows boxes and one FC2 Box on it. Whenever I switch to the FC2 box the mouse goes nuts -- opening windows and menus, jumping erratically etc. If I restart the fc2 box while on that port it works fine till I switch away and come back. I have tried resetting the mouse services, as well as setting the mouse to a generic 2 button serial mouse as was suggested, but I am not having any success. I could really use some ideas as this is an annoyance TIM Tim Holmes IT Manager / Webmaster Medina Christian Academy A Higher Standard... Jeremiah 33:3 Jeremiah 29:11 Esther 4:14
