the popup help menu also shows on a different screen:


that also applies to the popup help for the Library and Asset Browsers.
Windows 11 (upgraded from 10)
Two monitors @ 1920x1080
Revit materials dialog on the left hand monitor, popup help and menu appear on the monitor to the right.
If I move the materials dialog to the right hand monitor, then the popups and menu appear in the correct place.

It makes no difference which monitor the Revit window is on, just which monitor the materials dialog is on.
I only have two monitors on this rig so I can't test any further.
