Internet Explorer--debug

When I am on IE7 and have open a page or two, I get a message that says " I.E. has encountered a problem and needs to close. then is says "If you were in the middle of something the infomation may be lost. Please tell MS about this problem. We have created a error report to help us improve."
Then there is 3 boxes, first one says DEBUG, the second says SEND ERROR REPORT, and the third says DON'T SEND.
If you hit the degug button, it shuts down IE, if you hit send report, a little box comes up and says it creating report and then sends it and then it closes down the IE. and if you hit the third button it just closes down IE.
I have checked my the checked the debuging (scripts)boxes in the Internet Properties and I have also uncheck the 3RD Party Extenstion in the I.P. but makes things disappear like toolbars and stuff, and it also affects the way some other thing are displayed.
I am at a loss here. Would someone be kind enough to give me some help?
I thank you!
