Hello, I have placed the silent clean shortcut in the startup folder. All is well with that and it quickly cleans at startup just like it is supposed to but when it is finished, MRU Blaster does not terminate, it stays running (per ctrl-alt-del) and prevents a shutdown or reboot unless I manually kill it. The only other running items are systray and explorer. I have used MRU Blaster on many other machines and os'es but have never had this problem before. Any ideas? Thanks, ZR IBM 300PL Win98SE error-checked & defragged PIII-500 128mb pc100 8gb hdd w/7gb free no infestations of any kind.
