Hi I tried the suggestions and so far they have worked for my Lenovo Yoga 14 -- (thank Buddha and all of those who provided suggestions). I haven't re-installed the update as yet --- how will I know that its safe to reinstall??
I have a yoga 14, and I found a workaround that works after installing the update.
I followed the steps on Ged Traynor's Link, but when you get to step 3, you cannot configure the Wacom in the same way on the Yoga 14, because you don't have access to the same control panel. If you restart photoshop after completing steps 1 and 2, the problem remains.
So, I ended up following the Regedit steps in this reddit thread: https://www.reddit.com/r/Windowsink/comments/8508fi/controlling_pen_behavior_in_windows_10 /
This resolved the issue for me. I didn't go back and remove the file created in the Photoshop settings, and everything seems to be working fine, even with the update installed.
