Query: Discontinued Product

National Geographic has discontinued this TOPO! series in favor of their newer approaches to displaying topographical maps. They do not support the product on OS X Mountain Lion. NG and Amazon are still offering TOPO! for sale for a few states and unless you need and ask for support from NG the marketing does not mention it is discontinued and unsupported for the latest OS X.Since my FedEx delivery occurred to the wrong address and was not found for about a month it is too late to return the software but that is what it deserves.The concept of displaying topographical maps without borders is a good one and if the software worked reliably and was marketed honestly it would be worth about half of the asking price.
