Some time's i just want to throw my computer out the window

Thanks Soo Much!
lucky for me none of the other problems are happening like the taskbar and registry edit not opening up.

I also didnt have those problems, but I could tell it was running in the background and using my memory.. I think the bug that screws with the the task is different then whats going around now (ie. genric 9).. AVG works well..
