'Could not click Track Duplicate...': Duplicate audio macro failing

1. Install latest ProTools and Soundflow on a new computer.
2. Installed latest version of Soundflow (5.5.1)
3. Create new macro
4. Add action: Duplicate audio
5. Run macro directly from script
6. Duplicate audio window comes up on second screen.
7. Macro fails
8. This also fails when using my old macro which worked perfectly. Maybe a systems permissions issue?

The boxes for active playlist, Alternate playlists and Automation should be unchecked.

The macro fails with the error:

I have always run at least three screens on my system. Now I'm down to two. The Duplicate audio window always appears on my second screen. I'm wondering if the macro can't access it from there.
