Re: A quick update

Hello again,

The XCode project wouldn't open in my version of XCode.  This is just
as well--I'm starting to see the writing on the wall here and other
places and I think that it's high time I upgraded my system.  I've
been sitting here with the Snow Leopard disks, but haven't been able
to upgrade the system because I needed to keep a working system
working for the last few years and projects haven't let up.

I will re-approach this once I upgrade to 10.6.  If there are problems
then, at least they will be relevant problems.

Thanks again!

Mike
