Hi, I have installed Draftsight on my Mac (Catalina 10.15.7). I was customizing the UI: switched the UI, activated some toolbars etc. Then on a reboot I noticed all menus are gone. Command CUI / User Interface and I added the menus there again. All working well. Then I rebooted the program, and all menus gone again. Repeated the above, but same result after reboot. Reinstalled the program, but still same result. Anyone the same experience or a suggestion how to solve this? 

Many thanks!
