Degugging

i have a dell, with windows xp, it a new pc, no new software added, but sometimes i get a box that pops up when i am online and asks if i want to debug? i got idea what this is, or what to do with it. i did go into tools and
checked both boxes to disable it, but it still keeps popping up. i believe it has something to do with MS Office. if someone can throw me some info this way, it would be appreciated
thanks
