I love sharepoint and it is very nice and cool. We use it a lot to share information with our clients. But every know and then when I try to open or check out a document IE just crashes.
So I got tired of it and decided to put an end to that annoyance. I pointed my browser to google and found the: http://www.groovypost.com/howto/microsoft/ie/fix-ie-crash-when-opening-documents-in-sharepoint/ This post recommends running the Microsoft Office Diagnostics Tools and it really works.
If you cannot find your Diagnostics Tools use this page: http://office.microsoft.com/en-us/help/HA012340761033.aspx
