When I press the "0" key I get "Y" if press it a second time i get "yi", if i click the the trackball I get "uo", "esc" key gets "Hl" or "hl", "SYM" gets me a "b".
Also the way to make menu selection is with the enter key, very annoying.

To my knowledge it has not had any contact with any moisture.

It all good just had to sleeep it off!!!!!

Thanks for the input.
