I just upgraded to V4.4. When I import hdr pictures from Photomatix (stacked with the original) I get the #2 on one of the photos as I should. However, when I try to expand the selectioon by clisking on #2 all I get is 1 of 2 or the #2, I cannot see the imported hdr picture. I've even tried right clicking and expanding the stack but nothing seems to work. This worked fine in V4.3 so it is a new problem. I do a lot of landscape photography including panoramas and this is a real problem for me. Hopefully there's a simple solution.
Thanks for your help.
