Spinning in circles, keys not stuck

[Polyphemous]

I have a problem similar to this guy, but the solution doesn't work for me:

Last night after the server crashed a lot I had a problem logging in because when entering my password extra characters would periodically be added, as if a macro was running in the background. Example: if my password had 10 characters, after I got done typing 10 characters there would be 14... By paying attention and backspacing over the extra characters, I managed to get on with no further problems.

No extra characters would be added in non-EQ programs. I have no macro programs running.

Today, I haven't had a problem with extra characters being added while typing in my password, but all my characters spin in circles with an occasional step forward. If I hold down alt and/or shift I will stop spinning, but will resume as soon as I stop holding either key down.
