Just today, I started getting notification in a pop up box:
IE has stop working.
A problem caused the program to stop working correctly. Window will close the program and notify you if a solution is available.
And this is followed by actual closing of the current program on the screen. This does not pop up on all sites...just seemingly on selected ones including on line banking, live mail and yahoo mail... to name a few. (luckily Vista Forum site is not affected)
I ran MSE twice and came up clean. No malwares. The only software I installed prior to onset of this problem was Flash player 10..which I have since deleted to no avail.
