Not sure if this is your problem but when I made myself a screen set for my 12" touch screen I had
to cheat the system to get jogging working.
I did not want a button to turn jog on/off taking up precious screen real estate.
I
never want to
not be able to keyboard jog.
It's a tight squeeze on 12" when you want large buttons for fat fingers.
However I soon found that unless you have a jog on/off button on any particular page
then the keyboard jog won't work while using that page.
So what I did was make a jog on/off button that was 1 pixel by 1 pixel and hide it at
the very top left of screen and set it to "displays on all screens"
Now I can keyboard jog on any page but not have a useless button hogging screen space.
