My bottom bar on my desk top will not let me click on any of the icons. I have repair programs, but they don't open. I can get online using the icon on the home page, but the start menu won't open either. Any suggestions? My desk top was on both DSL and Wi-Fi, earlier I unplugged the DSL. It was working fine then, but then stopped. I tried rebooting, but that din't have any effect. Everything else seems to work.
