Sonoma iCal - Intermittent: Can't move events or OPT + Drag to copy events
Every so often, I can no longer drag calendar events to new times using the Trackpad, or OPT + Drag to copy events.
Instead of moving or coping the event, it displays one of those preview bubbles - see attached.
Quitting iCal usually fixes it (or plugging in a mouse) but not always.
What the heck is causing this mind-numbing waste of time - is it an update to M4 trackpads or a bug in MacOS Sonoma?
Does any one know how to fix? Any pointers in the right direction would be much appreciated.
Cheers
