0.99.7 Clicking on thumbnail does not open image preview (Mac)

[badgertog]

Hi
I downloaded this latest version for Mac 64 today replacing my previous version which was great.

The latest version opens OK and I can see my source folders fine but when I click on a thumbnail (any thumbnail) as I normally do to open a preview image nothing appears. The preview pane remains blank.

on which format?

Thanks for replying - I've managed to solve my problem
