I am repeatedly experiencing this bug. For me it happens when entering text in Script Text. Autofill options will be suggested, and if I hit Enter or Return before either selecting or clearing the autofill suggestions, I will immediately get a color wheel lock up.
Force quit will confirm that Avid is not responding.
Any corroboration or remedy would be greatly appreciated!
