What exactly is happening? Is the machine locking up? Is Mathematica
giving you an error message. I frequently convert Mathematica 2.2
notebooks to 3.0 notebooks without any trouble on an 8600 running Mac
OS 8. I'd be surprised if it has anything to do with the new OS since
many of the notebooks I convert are ones I have had lying around since
I was using 2.2 on an 8100 running 7.X.
