The new Mar-17 beta is not working properly on OSX 10.6 - if you're running 10.6 "Snow Leopard", there are some stability problems there with the new multi-touch handling stuff. You'll need to disable the multi-touch functionality in MoI by deleting one particular file to avoid sporadic crashes.

To do that, make sure MoI is not running, and then right-click on the app and choose “Show package contents”, then inside there go into drive_c/moi and there will be a file there named moi_touch.dylib – delete this file and that will then disable the new multi-touch event handling which does not seem to get along properly with 10.6 .

For the next beta I’ve automatically disabled the multi-touch handling when running on 10.6 .

This only applies to OSX version 10.6 Snow Leopard specifically, 10.7 and 10.8 are not affected.

Thanks,
