Would someone please tell Yahoo! that their "improved" email, despite the added storage, is a piece of dookie!!!

It's driving me crazy. If this continues, I'm going to have to change to another service (maybe actually start using my comcast POP account); I'd rather not do this given that my email address has not changed in 6 years...

In those 6 years Yahoo has been fairly realiable, but since this upgrade it's been spotty, at best. Don't they test these things before they go live with them?
