Hi, Ive been with ML 10.8.4 since I've had my new late 2012 iMac this summer. From day one, Mail and Notifications didn't make a good pair. In Notifications Prefences, I chose banners and alert for Mail. Works 1 out of 3 times or whenever ML choses to do so. Seems like Notifications has a mind of its own. Sometimes I hear the alert but the banner doesn't show. Then I see the banner and hear the alert, then I hear the alert but don't see the banner. Is this a common problem? Hints and/or solutions? BTW: permissions repaired. ML Mail always acted bizarre. Like the fact that no new messages alert is half the volume of the new messages alert...10.8.5????
