I've read about others having this problem, I've looked around for a solution but haven't found one yet. Whenever I have Mail open and then minimize the window, any time after that the main window randomly opens up again. There's no rhyme or reason to it. Its not checking for new mail at any interval. No ical or google events/reminders are set. I have several gmail accounts and one iCloud account. And I have no plug-ins or extras for Mail either. Its just very annoying. Has anyone else had this problem and solved it?
