I think it's your computer, Plotter. That or a visit to Spec Savers looms. Don't be afraid of system restore, it will guide you through the whole process and can be used to cure many ills. Try and make sure you choose your restore time before you started to have problems. I won't effect any of your settings/email/documents etc so is worth a try. I would agree with Diane about downloading stuff from the net, it could contain virus's but if you do it from a reputable site, such as the one I gave you, it should be fine. Speaking of which, have you run your anti virus software recently?
