zoom Hotkey [ctrl++] dont work.i cant zoom in when i work with animate cc..

hi,

my hotkey [ctrl ++] at xp-pentablet deco 03 dont work.

the hotkey [ctrl ++] also dont work with my keyboard!!

zoom in  with hotkey [ctrl+-] works fine.with keybord and tablet.

i can zoom out but i cant zoom in when i work with animate cc..

the tablet have a special wheel to zoom in or out.

the tablet is not defect cause the zoom works correctly on websites or offline picts ect.

in the tablet settings i set the hotkey [ctrl++] at one of the buttons - to check if the tabletwheel is defect.

but the buton dont work with [ctrl++].

other hotkeys are working with wheel and button.
