POP Peeper FAQ
If I'm using the option "Hide tray icon if mailbox does not contain messages", how can I access the POP Peeper dialog?
By running another instance of POP Peeper. This will actually send a message to the POP Peeper that is already running and tell it to display the dialog. If you don't have a shortcut to POP Peeper on your desktop, the shortcut is also available in your Start Menu: Start\Programs\POP Peeper\POP Peeper.
