Fenton,
I had FMP7v2, found the v3 update on the Filemaker site (no reference to anything later), installed it, and it works (meaning that text entry is at normal word processor speed). v3 had been billed on the Filemaker support site as, among other things, enhancing editing performance. So THANK YOU for the idea - it saves me from mild cursing and a bad attitude. I will indeed consider your other thought of upgrading to FMP9 after they get it to be happy with Leopard.
Fred
