In Quicken.app's "Securities" window, selecting a Security and clicking the "Price History" tab allows the user to enter Date, Closing Price, High, Low, and Volume. The "Done" button is default in BLUE, so I naturally click this button just after entering the data. However, the data are not entered into Quicken unless the "Add" button is clicked before clicking the "Done" button.
Please make the "Add" button prominent with colour, and also open an alert dialog box with something like "Are you really done without adding the data?" if the data exist in the fields but have not been entered into Quicken.
