same thing. Does not seem to recognize the numeric keypad (I am sure it is not blocked) ctrl+0 does not work either.
But, in the normal keyboard, it does work with the 0 above, f for fit, dash key - as zoom out, and I found a + to zoom in.
I looked at more feedbacks and someone has a problem with firefox so maybe I was not the only one. With FF doesnt work either, so there is no extension involve. Wacom drivers?
