Hi Martin,

Yeah that's probably the problem then - right now it's set up to use Arial and I had just assumed that it would be present since it's part of the stock OSX install.

There are a few variations of Arial, including stuff like Arial.ttf, Arial Black, Arial bold, etc... if you can get those back into your /Library/Fonts folder that should hopefully fix up that problem.

It's also possible to change the font that MoI uses for the UI - that's a setting in the moi.ini file, let me know if you want to change that and I will describe how to do that. Some fonts seem to cause problems though.
