IS ANYONE ELSE HAVING PROBLEMS WITH YAHOO ALL WEEK?

I switched to the new yahoo on monday (by accident) and unfortunately i can no longer go back to the old. Since I've done this, I am having having SOOOO MANY PROBLEMS!! It is constantly freezing, booting me off, not attaching pic & docs, can't compose emails, can't respond, and everything else that can go wrong at one point or another does!! I have not come in the office yet to no problems trying to read my emails. It's like it's got a mind of its own!!! Is this happening to anyone else??
