Query: Take a pass, especially if you have a Mac

It specifically states on the box that it will work with Leopard, but it crashes every time I open it before I can actually do anything. Quickverse does not acknowledge this software on their website, and when I asked for help through their automated online support request, I got back a canned answer about a patch coming out for their other products, but no mention of this product. You can email Sales, but not Support; I emailed Sales and asked them to forward it to Support, but I never heard anything back. Granted, I paid $10 for this software, but it has very limited features, and I refuse to do business with a company that provides poor service. If you have a Mac and cannot afford Accordance and cannot wait for Logos, Quickverse products are your main option, but get the 2007 White or Black box edition - at least they acknowledge those on their website, and there is a patch to make them work with Leopard.
