"Sounds like" your security settings in IE need to be reset to the default, or could just be MSN, when it comes to them I personally give them le-way (2-4 days) or more, lol, before I try fixing or tracking down their problems seems like by the time I get done trying to repair or think Im onto the problems they have ... next thing ya know ... stuff starts working again. By all means post back if this isnt helpful.
Good Luck!
