Okay, i was using XP Pro and all was Ok then my mouse starts going nuts and opening apps whenever i float over them, then the mouse pointer just vanishes and i cant get it working again. I have noticed that the Mice and Other Pointing Devices option in Device manager has now disappeared, along with my driver for my mouse. I have tried downloading Intellipoint from Microsoft for my mouse (its just a Basic Microsoft Mouse) but this dosent help. Its NOT a virus as i first suspected cause ive scanned with an uptodated Norton AV and it checks out fine. I have also tried another mouse with no luck. Any ideas????
