Hi Gav, yeah most apps do not have MoI's same ability to scale the UI to any arbitrary size, so that "full screen resolution" method probably won't work too well as a full time mode.

But if you know that you are going to spend a chunk of time in MoI then doing that resolution switch may work for now anyway.

Can you test something when running under the regular Retina resolutions - what happens if you right-click the MoI .app and then pick "Get Info" then on that panel that comes up in the "General" section near the bottom there should be a checkbox labeled "Open in Low Resolution". Is it possible to uncheck that or is it grayed out?
