I just noticed a strange keyboard behavior. I don't know it it is just a hardware keyboard problem or it's a common issue.

- When I hold toghether "r" and "t" keys and press "w" key holding "r" and "t" pressed, caps lock turn on or of

- When I hold toghether "r" and "t" keys and press "u" key holding "r" and "t" pressed, the letter typed is one time "y", one time "u"

- When I hold toghether "r" and "t" keys and press "e" key holding "r" and "t" pressed, the sound volume is increasing

- When I hold toghether "f" and "g" keys and press "j" key holding "f" and "g" pressed, the letter typed is one time "h", one time "j"

-The same strage behavior is for "v" and "b" keys holded toghether

So strange behavior for "r" + "t", "f" + "g" and "v" + "b" holded toghether + a next to them key pressed (in the left or right of the group) is just for me or anyone else does have it?
