It seems Rory & I aren’t the only people to notice the bug in RAW support in Tiger… There’s quite a few other people talking about it on the discussions forums at Apple now (although I must admit I admire Apple for providing public discussion space for their products - even though some people do complain about things they dont like - and other’s see those complains… imagine if microsoft.com had public forums on their site for people with Windows issues :P)
