setup on OSX ignores button clicks

[Timothee Besset]

Anyone ever experience the following behaviour on OSX port of loki_setup:

Setup starts up fine (launched from an xterm, with X11 active and proper
xhost / DISPLAY etc.), displays the license prompt, but you can't click
any button. The visual feedback shows the 'Cancel' or 'Accept' button
being pushed, but nothing happens, no going to next screen..
