I've had this problem for years. In the Reconcile window, the default sort of your list of Payments and Checks is the Transaction Date (the date I entered the transaction). When clicking on the "Posting Date" column, nothing happens but the appearance of a blue arrow showing the sort order (Newest to Oldest/Oldest to Newest) but the sort is still the Transaction Date. In other words, sorting by Posting Date still results in a sort by Transaction date. Any fixes for this issue? I've had it for year.
