Ive been slowly testing C1 pro on my new Leopard machines and I've come across a serious bug. When Processing files some images have black horizontal blocks through them (see attached image) Its seems totally random and happens on both a 2.6 MBP and a 2.8 MP. It also happens on two sets of P45+ files. The Raws are fine, and If I process the same folder twice different images will be bad. Also, if I have more than one Destination say a jpeg and a Tiff they will have the bars in the same place. Baffling. Tried 3.7.7 and 3.7.8 Anyone else having a similar problem?[attachment=5002:attachment]
