I was having a heck of a time with Sharepoint. Every time I would click on a document, my browser would crash. The only way I was able to get a document to open was to right-click on it and open it in a new window. Needless to say, this was really annoying!
I found a Microsoft KB article that solved the problem.
Just in case someone searches the interweb with the error code I was getting, it was: 0xc06d007f.
