I'm on Quicken Classic version 7.7.1 on macOS Sonoma 14.5.
In the past day, my Quicken has developed a noticeable lag when making just about any change to a transaction — setting transaction status, reconciling, editing, etc.
Whereas changes formerly occurred instantly, now I get the Mac beachball spinning for a couple of seconds before the change commits. I cannot think of anything in particular that I did or changed that would have initiated this behavior. The only thing I did lately was try out creating some new reports.
My Quicken file has data back to the 1990s. Not sure if it's too big?
