The latest update still isn't compatible with Catalogs created in iView MediaPro v1.5.7.

On the plus side, a much-needed feature has finally materialised - the ability to edit captions in list, thumbnail, and full views without having to open the Info pane. Just click on the caption and edit it like you always could with filenames. I requested this feature more than a year ago and I'm glad they finally got round to implementing it - let's hope it doesn't take so long to fix backwards compatibility with v1.5.x Catalogs.
