iMovie drop down menus not working
Since upgrading to Catalina, iMovie drop down menus are not working. If you select any of the top dropdown they appear an illegible pink or purple color. and do not respond to a click. I have tried rebooting the iMac and deleting and reinstalling iMovie but no joy. Cannot even access the force quit on the apple drop down when this happens. A power off reboot with the power switch ins the only thing that restores everything. Does anyone have any clues as to the problem? Thanks in advance for any help.
