tablet pro

JoshB,
I have SP3 as well. I find that hover modes with the pen are only detected when the pen has touched the screen once and or you are close enough to get the circular cross hair. Then you can hover the pen from the screen about 0.5 cm (at ~ 1cm the pen looses detection with the display). You can then press the TabletPro hotkey to initiate middle click + alt.

IF you touch the TabletPro Artist pad key first and then bring the pen into range of the display the pen will not initialize, As windows has taken the touch as the primary interface cursor. You will have to release the Artist pad key so the pen will initialize the cursor and then you will be able to press the key.

Do you find this happens?
