thanks for fixing this so quickly.
this seems to work for me. the 3D view is fine now, and there's no need anymore to change settings for the X11 in order to make it work.
I'll try the update in parallel with my current version and let you know if there is any problem with 10.6.8. It may be a few days before I report back as something big has unexpectedly dropped in my lap.
Hi Lewis - the current version of MoI for Windows is still MoI v3.0 - the version 3.1 release is for the Mac only to fix problems with running MoI on the latest Mac operating system.
