I am running Photo Mechanic Version 6.0, build 3558 (afa5073) on an Intel-based Macbook Pro Mojave 10.14.6
I am using a Wacom Intuos S graphics tablet with up to date driver version 6.3.36.2
When in the preview mode and using the graphics tablet, ⌘-click zooms in, but when I ⌘-click again, it does not zoom out.
It zooms in and out again correctly if I ⌘-click using the trackpad.
Trackpad clicks are reliably recognized when performing other functions in Photo Mechanic and other software.
This is a new problem that was not present last month.
Thank you for your help.
