IEXPLORE.EXE - Application Error

I have a problem with IE 7 running hard and when closing the browser I get an error message (see attached picture). I notice the browser slowing down about an hour in use. I checked the windows task manager and iexplore.exe Mem Usage is high around 160,000 - 250,000 k. What could be the problem and how can I fix it???

Hi grave It is probably due to a bad plugin or addon. Reset Internet Explorer, and see how it goes. In IE, Click tools, then Internet options Select Advanced tab Goto Reset Internet Explorers settings, click the reset button. Restart IE Regards

That worked. Your awesome, thank you very much!!!

Np at all
