I have used keywords in Lightroom, and it was no problem.
In Capture One Pro 7, they don't seem to stick. I select all the images I want to add a keyword to, go to the keyword tab in the metadata panel, click plus, enter the keyword, hit enter, and then deselect the images.
When I go back, a few of the images have the keyword, most don't.
Why isn't this working? What do I have to do to get the Capture One Pro 7 catalog to accept keywords for all the images they are intended to?
