Have current Quicken file working perfectly. Open an old archive year end file where data is needed for that prior year for tax purposes. Go back to the original file. The data from the two files will partially merge, accounts are all messed up accounts disappear, updates pull down all data again - terrible things happen. The only way to get back to any semblance of where things were is to do a restore to the current account from a backup several days old. Even Sync settings gets messed up. This should not be the behavior. Opening an old file should not cause it to partially merge with the current file. This is just unacceptable behavior, and it is not a new problem. For the record, during the last year I have kept a spreadsheet of all my banking and finances because I can complete my work in the morning in 5 minutes, whereas I have to wait all day sometimes for Quicken updates to be current so I can do my finances if using Quicken. Quicken adds work rather than saving me time. For the record, I will not be renewing your product this year - and I have been a client of yours since DOS days. Your product is very poorly designed now when opening an old file messes up the existing file. Archive year end copies should not affect current copies. I suggest you fix things like this before you lose more clients.
