I've been playing around with Zimbra Desktop the last couple of weeks, and just upgraded to the latest version (build 1338). I can't seem to get pop-up notifications for new mail and calendar events to work under Windows XP. Either that or I don't understand how they should be working. I've got "Show a popup notification" checked on both the Mail and Calendar tabs under preferences. I have Zimbra Desktop minimized to the system tray with a couple of other programs running (IE and a Telnet app). While working in these other programs I would expect to see something come up on the screen when new mail comes in or when a calendar event is triggered, but I get nothing. The only thing I see is the red "Z" icon in the system tray turns to an envelope when a new unread message comes in. What am I missing here?
