Hello,
we have the same issue with the newest Version (DMRC) 12.3.1.20 to switch between 2./3. Monitors.
You can click the button to switch to a secondary monitor, or the virtual monitor, but it just stays displaying the primary monitor
This issue was discussed 2 years ago with the Version 12.3.0.12 here.
Does anyone else have the Problem?
Thank you
Martin
