When I try to log into my store (not in the admin section) I use Lastpass. When I do, I get a screen telling me to fill in all the fields for my order info without logging me in. If I type my email address and password manually, I'm in.

I go to a lot of sites and forums daily that require logging in and Lastpass always works for them. I can't figure out what's going on. If it helps, when I click on "logon" from the home page, and then click the button Lastpass provides at the top right of the screen, I am whisked off to the order info page.
