same problem here
I'm having the same problem. I am using Firefox on XP. The homepage doesn't allow me to sign in. I always have to click on the "my account" link at the top to enter my log in information. I have tried both the enter button and using the mouse from the homepage. Neither works for me. Odd thing is that sometimes it works on other computers from the homepage, but not ever from my home computer. I have no problems at all on IE.
