I have no viruses, all software, flash, drivers
, and BIOS are current. I have no gagets running, have all animation and effects turned off. The simplest example is trying to click on the taskbar icon for sound to mute or change the volume. When I try to move the cursor to the pop-up, it disappears. Same thing happens with maxmized windows, I cannot use the taskbar icon to close them. The pop up disappears when I move off the task bar. When composing email in Windows Live Mail , I cannot keep the cursor in the Subject line to type a title. (To get the subject line for this email,I had to type it in the body and cut/paste.) The mouse focus shifts to the body of the email. I have tried USB mice, cordless mice, trackpad, all do the same. H E L P !!!!!!
