LOL, cat jumped up on my desk last week and spilled coffee w/ cream & sugar all over my mouse and side of desk, mouse pad etc...

rinsed, cleaned & dried it but still wasn't working right , so got spare one from laptop and it worked fine.

then tried the old one a few days later on the laptop and it is fine now..

so yours might be OK again after it gets all the way dried out, or did Ivan keep it?
