Hi all, hope someone can help. Here goes. I have a Dell DM051 that I was using a Belkin KVM switch on. I removed the switch and connected everything back to the computer and everything appears to work fine except the mouse. When the computer starts up and gets to the windows XP log on screen, I cannot move the pointer over to my icon to select my user so that I can enter my password and continue. So, there I sit, on that blue XP log on screen, looking at the pointer that I can't move, beside the icon that I cannot select to continue. Any ideas?? And while I do appreciate all help, please don't ask if the mouse is connected or stuff like that. I've tried several ideas from diffrent mouses to removing jumpers and batteries, etc. What I need is good advice from someone who knows computers. Thanks in advance, Phil
