Ick... ;-)

That really is a hack...  ;-)

Ok.. thanks... I was hoping more that you'd figured out how to read the data files directly..

BTW... you might want to download a free copy of vmware to run a windows "guest" in.. you can iconify the guest, but still have mapsource running as the top program on that windows guest. I've got about 6 different guests running on this box now, and they all work like a champ.

Nice job on the website.
