I'm running XP Pro with SP2 AMD 1.15 GHz, 1.00 GB of RAM
My problem is when I try to run the Yahoo IM I only see the hour glass for a slight second before it's gone and nothing happens. I haven't had this type of trouble with yahoo ever before. This also happens with Pest Patrol. As far as I can tell everything else is running fine. I've ran my anti-virus program (AVG 7 Pro) which shows no viruses. I've defragged, ran my spyware with no changes any suggestions?
