Photoshop zoom sensativity

[PhilDLowe]

The zoom sensativity on my cintiq 22HD has just gone up to uncontrollable levels.  I can zoom from .10% to 150% by barley touching the screen.  The touch strip on the side isn't much better, and I have that set for brush size anyway.   I just updated to the new 2018CC and also updated a new WACOM driver, so I'm not sure where the problem is coming from. I don't see any way to adjust zoom sensitivity in either the Wacom control panel or in PS.

Running macOS Sierra version 10.12.6 on a late 2013 iMac - and I just updated to the newest version of photoshop (19.0) release.

Any suggestions?  In it's current state, the touch zoom is unusable, and after zooming this way for years, I don't know if I can undo my muscle memory.

--Update--

The zoom gesture stops working completely after a couple minutes.  If I restart photoshop it will work (though with the same sensitivity issues) for a couple minutes before it stops working again.

I have seen this with the latest Wacom Driver on 10.12.6. If I downgrade the driver to 6.3.24-1 (available on the US Wacom site under previous drivers) instead of the current 6.3.25-2 the pinch zoom works much better.

That did it. 

Thanks!
