I have "Show a Pop-up" feature enabled under "When new Mail arrives" - nothing else. Isn't this feature supposed to allow you to continue working in another application if you click "OK" rather than "Open Mail". For example, I'm working in Excel 2003 (Win XP) and new mail arrives. The pop-up window appears in Excel and when I click OK, I'm taken to the Notes Mail window. Sometimes the pop-up window doesn't appear at all - not sure if this is because I have check for new mail every 15 minutes... Have I not set this feature correctly? or am I mistaken on how this feature is to work?
