After I updated to the new SVN patch, it seems that during slideshows, the pictures that are of smaller resolution seem like they are not as 'zoomed in' as they were before. It might be a simple problem, but what might I be doing wrong?
I think if you push page up and down you can zoom and then arrow keys pan around? This was how it worked with 0.2 release candidates at least, I haven't touched My Pictures for a while.
Edit: This only works for viewing one picture in closer detail from a slideshow. Perhaps you were talking about a global zoom that would be the default for slideshows etc.
