Weird Keyboard Problem.

Well a friend of mine isnt able to type proper sentences ... no he isnt drunken and there is also no changed Windows Language Keyboard setup.

it looks like this when he holds a single key:

[16:36] J.P.: bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbc

Or This: "Wer ist die Katze die an der Tür kratzt."

[17:02] J.P.: wxecrvx ist die katze xdie an der tumecrv xk,rvayytczvtc


so he is pressing 1 key -> output 2 chars which are close together on the keyboard.

Edit: Notebook and usb-keyboard got the same weird output.
Edit2: No he dont have "Sausage-fingers" he is really pressing 1 key ^_^
