When I activate CleanUp3 the SU window darkens but there is no dialog settings box.
I can right click to close the dialog.
I have reset my workspace, uninstalled and reinstalled the plugin and repaired SU as administrator.
Alt+space>move doesn’t work.
The difference between now and when it was working is that I have a new PC + new monitor and 2 existing monitors (my previous setup was also 3 monitors).
I have gone into Windows display settings but there is not ghost monitor.
