Login and logout are broken on new Y7 homepage.
Log-in links from Yahoo7 homepage are terribly slow to respond, then the log-in dialogue box page is even slower, totalling 2 to 5 minutes to log in. Generally try clicking the login link a second time, because it shows no sign of loading. It briefly flashes that I have used an incorrect password, then reverts to the homepage, with the login successful.
Log-out from the homepage is impossible. You have to click (not hover) on the mini-profile pic to bring up the log-out link. But the link appears only momentarily, because having clicked the profile pic causes the page to reload, and log-out has not been achieved. To logout successfully, we have to first go to our email page. The logout link there works properly.
