Anyone having trouble with Yahoo Groups?

Is anyone else having problems with their Yahoo Groups? No problem with Yahoo Mail but when I go to a group there is a new format - on the left listing all my Yahoo Groups. I can get into the group but when I try to read a message by clicking on it or answer a poll I get a word at the top of the page that says loading and it never does. As a result I can't access my Yahoo Groups. Looks like they may have a new format that isn't working properly. Anyone else have this problem?
