Emulating in low resolution on Retina.  Thanks anthonyirwin82!  
Also a quick reminder to all to update the Shader Toolkit for VS 5.  Here is the link SimonS provided in another post- 
The new shaderscript is here: http://rollaprint.de/vs/shaderscript9.lua
Do I need to update?  There was an update option the first I opened.  I don't know what triggered that.  I saw it again- and was able to select it, but the update app canceled- I think due to the orignal install disk image not being mounted?  
I will try a fresh install and see if that cues the update.  Thanks!
