Leopard Login Problems - Incorrect password with no input

[Unubis]

Hi guys,

I'm having a problem with my macbook running leopard. When it gets to the login screen, the login box will constantly shake as if I have just entered an incorrect password. This occurs automatically as soon as it loads (i.e. no input from me)

While this is happening the password box will clear itself after every shake which makes it impossible to enter the password. I managed to get on this time because of luck I think - I just left it doing it for a long time and it must have got bored and given up 🙂

Has anyone ever heard of this problem before, or seen any solutions?

Thanks

Sounds like a stuck key. Spilled anything on your keyboard?

Nope, no spillages.

I tried opening Word to check for obvious stuck keys such as letters or return, but nothing happened with both the in-built keyboard and my external mac keyboard

It was working fine this morning, and then I went on a train journey, booted it up at the other end, and this error greeted me!
