Hi laser2sail,
> Options | Viewing Options | Window | Fit images to window width & Maintain aspect ratio
Thanks for your reply. I'm afraid it's more tricky than this. When I do what you suggest, it does come up without black borders, but it comes up in a window that is way too big, compared to the resolution, and where I only see the top of the picture.
What I want is that it comes up at the right size, reduced if necessary to fit the screen, and without any black borders.
In TP7 "reduce images to window" worked.
