Flame 2023 weirdnes with two screens, Mac

We’ve installed 2023.0.1 on MacOS Monterey. iMacPro with ultrawide monitor as the main screen.

The keyboard/mouse/tablet doesn’t work on the Flame UI so we can’t even start it after we close “What’s New” splash screen (it works there).
If we use the iMacPro screen as the main display, everything works. Mirroring the displays works but then we can’t utilize the ultrawide display.

Any ideas?

Make your wide screen display the main screen (with menu) at the OS settings.

Go to System/prefs/display and in arrangement drag the little menu bar item from the iMac Pro over to the widescreen monitor.
