I have tested with 10.4 & 10.5 on the same Core Dou system, so not really a Leopard issue. It seems to be the Core 2 Dou that is causing the problem I suspect.

Since, I have only tested on Intel Macs, nice to see some other's results :) Cheers --- Norman Franke <norman at myasd.com> wrote: > It may be a problem with Leopard.
