In a brokerage account, I elected to sweep my cash into a money fund. Quicken asked if I wanted to track the fund as cash (recommended) or a separately managed security. I chose the recommended action. When I reconciled the account the cash holdings were off by several hundred dollars. But more concerning, the cash holdings for many years prior were changed. Reconciled balances were now hundreds of dollars different. I checked a backup to ensure the balances were correct in the past and now changed. How is it possible for Quicken to make changes to historical reconciled transactions without any approval or confirmation?
