FWIW - installed 515 on a different 10.9.3 Mac (Late 2012 iMac) and DID NOT experience the snap label issues reported here and in the other thread below.
Question out of curiousness…noticed on both machines, first launch of 515 took extraordinarily long, like something is going on under the hood? Thereafter, 515 launches in normal time. At first I though my system was FUBAR after an update until I waited it out.
