[Dundas, J. <JD...@ga...>]

Hello
I have a user getting the following error on connecting using OpenNX on a mac that was upgraded from Mac OSX 10.9 to 10.10.

Not sure if this problem is on the OS side or on OpenNX.
OpenNX appears to make a connection but fails to launch X11 and returns the log on screen.
Any ideas on what to do?
