My corners are greyed out. How do I get this back?

I can no longer use the corners features in CorelDraw 2020 or in 2021? Does anyone know how this has happened?

  • Fixed it!! It was a simple matter to reboot my computer. Both CorelDraw 2020 and 2021 are now working correctly. I think it was a re-install of software for a Roland Wide Format Printer that caused the problem. I downloaded a software update for the printer and then nothing worked on the Roland printer. I needed tech support to re-install the printer software and the Roland is now working great. Seems like software updates are driving my print drivers crazy!
