While it can be handy to receive a notification when you receive a message or call—and especially when you've missed one—it's irritating to see it when the message is no longer new. But that's what happens if you "hide" the notification in Windows Mobile.

So, instead, when the notice is showing, tap "dismiss" in the lower-right corner of the screen.

Interestingly, even if you have deleted the message and your inbox is empty, you can still see the notification pop up if you haven't actually dismissed it. This feature sprouts for new e-mail and MMS messages and for missed phone calls.

The "notification" message switches to "hide" while you're viewing it, which is why the "dismiss" button doesn't grab your eye. But it's there, quietly on the right, waiting for you whenever you decide you've had enough of the reminder.

Just to keep things interesting, if you're using the mobile version of Outlook and a reminder pops up for an appointment or task, that notification has the "dismiss" button on the lower-left side of the screen (with "menu" on the right). Apparently, you're not to be tempted with the option of hiding you're responsibilities.
