Hi, Every time a notification comes in the Notification icon in my menu bar disappears. I can still click in the blank space and it fires up my Notifications tab and the icon reappears until the next one comes in. To be fair, this is not new to Yosemite it used to occur under Mountain Lion too, but with notifications becoming a bigger part of OS X this is starting to get annoying. My icon is on the rightmost of my menu bar, I run Bartender but it occurs with or without BT running. First of all has this ever happened to you? Second, any idea how I might go about fixing it because I don't have a clue? I thought I might try to find where the icon is stored in OS X and muck around with it but I couldn't figure out where it is saved. Thanks.
