Mac UI hangs quite a bit.
I'm new to gamesalad and have only been using it for a couple of days after downloading from your site. From day one, the UI seems to slow down to a painful pace and hangs for 10+ seconds at times when navigating between scenes or from a behavior view back to a scene view. I'm an experienced rogrammer/developer, my macbook pro is Mid 2014 Intel Core i5 2.6 GHz 8 GB RAM OS X Yosemite 10.10.2. I'm finding it hard to imagine using this when productivity is a concern. Is there a known problem?
