ip intruder? Mouse acts weird only at certain times, closing browser windows - same ip, different laptops, different mouses.When I'm online - even on different laptops - my mouse keeps trying to close my browser window, either by moving to the top right of the browser and hitting the X button or by moving to the top left. This does not happen ALL the time (maybe when the intruder is in a having fun mood) but it's very annoying. I've tried different laptops, different mouses, but since they all use the same ip through wifi I'm thinking that I may have an intruder. I've checked for malware with no threats. What can I do?
