Hi, I am experiencing the exact same problems as the original poster after upgrading my Mac to HighSierra. Was working fine before the upgrade, but after the upgrade I get an error when opening TaskCoach. Fortunately, after clicking "OK" it will load and display my tasks. When exiting it will close the task list but leave the "frame" on my screen. Seleting to quit TaskCoach again will display a prompt that there are unsaved changed and ask if you want to save before closing; however, selecting "Yes"...
