I'm running Quicken Classic V 7.3.1 on macOS 12.6.7 and all of the sudden I can't reconcile accounts.
Why not? What's happening? Have you previously been able to reconcile? What type of accounts?
I can't either. I just updated to Version 7.3.1 (Build 703.50428.100) on macOS 13.4. When using the reconciliation feature, none of the activities for the selected period (9/1/2023-9/30/2023) are selected/displayed in the reconciliation window and marked as reconciled when I press "Finish" nothing gets marked as reconciled.
Actually, I take that back, pressing "Finish" does seem to mark the items as reconciled in the register, but they are not displayed for reconciliation in the reconcile window.
OK, sorry, for another register they are being listed. It's possible I missed the items the first time and subsequent times they were already marked as cleared/reconciled. Only thing I can think of as this looks to be working for another account.
