Michael,

I have been using the Mac OSX version a bit more and I have run into some stability problems. My file size is 243.3 MB, and I have been getting frequent "insufficient memory" warnings when exporting, followed by objects missing in the files. I have been able to recover most of my work in the bak.3dm files that show up afterwards but it is getting a bit frustrating.

I am in the process of breaking this file into several smaller files to see if this helps. Just thought I would report the situation.

This is on a one year old MacPro 2x2.4 GHZ Quad core machine with 12 GB ram. Cheers
