I'll try IE and see what happens. I use Firefox, which has it own quirks with the new forums. Photo resizing being the biggest (as in big photos not resizing) one.
By the way, I noticed you were clever enough to match the background colour for your 3 stars, I hope you don't mind if I borrow it!
edit I'm editing this post from IE (shudder) and tab took me to the password line as you would expect it too. I'm at a loss to explain why it doesn't for you guys! /edit
