I noticed a strange issue when I have Harmony full screen / maximised on Mac and I create a new palette. When the field to name the new palette pops up, it stretches to full width of the screen and the rest of the application is minimised. I have to either click on the Harmony icon in the Dock or Cmd+tab to bring it back. This only happens with Harmony is full screen, as you can see in the quick video below.
I’m using Harmony Premium 12.2.1 and OSX 10.11.3
