Every program keeps minimizing to the system tray. Any fixes?

It's a possibility thats a feature in WindowsBlinds you selected on accident or with Hotkeys. You can try what one user suggested which is to unistall WB to see if it corrects the problem. It could also be a feature you accidently turned on for your Graphics Controller... go into Control Panel/Display and find out what "application" controls your monitor, then check in Control Panel again and see if graphics application can be modified (review it and see if there was an option you accidently turned on). Third run a virusscan (though it sounds unlikely). Fourth run a "sfc.exe /scannow" (you will need your XP cd if the program finds any operating system files that are not correct).
