There has been an issue about IE crashing since the latest updates from Microsoft. There is a fix ( if that is what is causing it) but it does involve a Registry alteration which, since you are here in AB, you may not feel confident about.
I have read that MS have issued a further patch and it is available for download.
Try first going to the MS update site and see if it is offered to you. Always a good thing to check under "custom" update for the full range of options.
