AFter further testing, This problem occurs when using the Asset/BP Editor window “maximized” (which is my preferred view for working in bp’s).
after a short time, the right click menus and popups stop working correctly.
Tested this several times, and also used the editor without any issues all of last evening in “minimized” view. Switched to Maximized and it broke.
Once the problem starts, if I Minimize the Asset Editor window again, right click and popups work intermittently.
A restart of UE5 editor is required to resolve it.
