Hello to all

I got a stylus for my Portege Z10T-A (PT141E) purchased, original from Toshiba (pen PA5133U 1EUC).
With my Z10 no stylus was at the time of purchase, which didn't bother me...
Now I wanted to try it but once.

But he is not recognized by the system.

My Z10 works as far as trouble-free until the chop my towel in the display at does.
