Login error or normal pop up?

[Nash Latkje]

While trying to log in this morning... i entered my username and password as usual... and then a box came up out of nowhere saying something like... enter your username and password to enter the password protexted area in suikox.com... this should be the username and password box at the bottom of the site, but after i did that something else came up and sent me back here and kept doing so for quite a long time during the morning...

it was just a simple popup style grey box in the middle of the screen... any ideas? :?
