I am waiting for a reply from the company. They have made one SERIOUS error in GS4 -- I can no longer search my own auctions for my own product codes, which effectively means I cannot use the program that I paid for. In the past (excellent) version, I could open it, search for "PHS610" (my own product code) and find the auction to relist immediately. This fundamental, basic functionality is broken in GS4. Sadly, while this is a fantastic app, the company is just not good about replying to customer concerns or making changes that we need/ Thus, I cannot recommend this version at all.
