Removing a 6.5 Lock password

[Kirbysuperstar]

At first I thought the password was neat, but now I'm sick of typing it in. Unfortunately, whenever I go to Lock in Settings, it comes up with the lock screen's password prompt, but there's no button to accept. Just the numbers, backspace and a non-working cancel button. I have to do a soft reset to get back to the Today screen when I do this.

I had a poke around in the registry, but I couldn't find anything. Anybody got any idea how to berid of this? Phone's a P3600i using... uh... someone's ROM. Can't remember.
