No idea what I could have done - captioning (using "i" then save next to move) and first image was normal, hit save next and the image appeared and then went all black (looks normal on contact sheet), next image the same. Closed out; reopened and still happening. Same thing also occurs when I click on magnifying glass - large image all black, filmstrip at bottom normal.
PSD files - Windows XP Pro. PM 4.6.1
Thanks for any help.

Edited to add - saved images as .jpgs and they are now fine, BUT my normal workflow involves captioning while still .psds and it has always worked fine so I'd still like to know what has gone wrong. Thanks.
