I am hoping someone can help with a problem I have been having for a while now. It doesn't seem so bad but it's pretty annoying. Very consistently while I am working or surfing, the screen I am on is no longer the screen on top. For example, while typing this text the computer suddenly dings and the cursor is no longer blinking in the text box and this internet window is no longer highlighted. If I alt/tab then I go to the last window that I was on and if I do it again I am back to this one. In the span of the couple/three minutes that it took to write this text it has happened three times. I ran ad-aware and norton to no avail. Can you help me learn how to track down what is causing this? Thanks
