After starting QuickBooks and logging in, QuickBooks immediately minimizes to the task bar.
Note: If you have not set up users in QuickBooks, the program may minimize immediately after the program starts.
QuickBooks retains the status of the program window at the time the program was last closed. In this case, the last time QuickBooks was open, the program window was minimized to the Windows task bar. The user then right-clicked QuickBooks in the task bar and selected close. As a result, QuickBooks now defaults to a minimized status.
