Hi, Today I made my first tests on Windows converting v1 file to v2. It works but it is very slow. On Mac, it takes 7 seconds. On Windows, it takes 180 seconds (3 minutes) The file is small, 1.8 Mb, about 1300 records, a dozen of tables. Is there a reason for such x60 difference? The PC is A P4/2Ghz. The Mac is a Quad 2.5 Ghz. Stan
