I've successfully been able to lock the Y-axis using a Modifier key (Ctrl) in the Default profile settings. Now I would like it to occur only when using Photoshop.
To do this, I made a copy of the Default profile where I had the working settings, and identified Photoshop as the app for the copy, and saved. Then I went back into the Default settings and 'undid' my working settings - unchecking 'Enable modifier keys' and setting Lock Y-Axis back to 'None' for the control. When I did so, and went back to my Photoshop app settings, it changed there too. When I re-checked the checkbox to "Enable Modifier keys" and reassigned Lock Y-Axis back to 'Control' in the Photoshop profile, sure enough, my Default settings profile reflected the same change.
What am I missing? How do I enable and assign Lock Y-axis to a Control for just one app (Photoshop in this case)? Is there another setting or checkbox other than 'Enable modifier keys..." that I need to set for each profile to control when that occurs? I realize that the controls I am using are in the "Global Settings" area, so would like to know if there is a better method or settings I need to set in each profile to control this.
And yes, I am pressing OK and applying the setting on the main screen after each change...

Any help appreciated.
