I'm having a slightly odd problem to explain. For some reason the selection of whichever window I'm in, wether explorer, a folder or a program quits every second and I have to click again with the mouse over it in order to continue working.. For instance, if I want to type in this text I need to click every second on this window because the explorer window quits its selection and therefor I can't type unless I click here again. every once in a while it stops and I can work again. I scanned the computer for spyware and viruses and everything is fine. I'm using Windows Vista Home Basic and this never happened before What can I do? Thanks.
