Digital Light & Color

An update is available to Version 8.0.72 (23-Mar-2020)

This update fixes a serious problem in the previous release:

Fixed problems with black image display in some cases.

Yes, thank you, that fixed it. Is it odd that on my laptop 8.0.71 was fine but on my desktop it wasn't?

It worked OK with highlight and shadow clipping on. Or with color management off.
