Horizontal Scroll in Viewer Doesn't Work on Mac

I am using Studio 17.2.2. I used to be able to hold down Command and scroll my Apple Magic Mouse left and right to move the Player Window/Viewer horizontally on all pages. It doesn't work anymore.

Can you please help I am on the latest version of Mac OS.

You dont mention whah version you moved from. . the 17.2.2 manual on page 63 listed the new mouse, trackpad and pen and tablet controls. have you tried two finger pan?

I think Peter means page 63

Get a nice three button mouse and enjoy. The ‘magic’ mouse is a drag in DR.
