When I preview all my pictures (usually when I want to quickly see all my shoots and remove all those I don't like...), I usually use the preview mode, along with the thumbar, and use page down to switch from one picture to the next one.
However, when there is a movie in the album, the behaviour is not really as expected

Reproducible: Always

Steps to Reproduce:
Take an album with 3 pictures and one movie : A, B, C, D, where B is the movie
open the "preview mode", enable the thumbar, click on A, press pgdown.
The movie gets selected, and played.

Actual Results:  
-the movie takes the full panel (the thumbbar has disappeared) : it is probably normal, but not really what I would expect : why does the movie make the thumbbar disappear, and not the pictures? And what if my album has only movies in it?
-furthermore, "page down" does not work anymore. The only solution to switch to "C", the picture after the movie, is to use the "next picture" blue arrow  (argg, I must take my mouse back in my hand, what a suffering!! :-) )
-If i do that, the thumbbar reappears, but is still not focused : Page down still does not work

Expected Results:  
-Don't hide the thumbbar to play movie
This should also prevent the thumbbar from losing the focus, which is very likely the reason why "page down" does not work anymore
-add a preference "play movies in full panel in preview mode" : that may be a good idea, but won't solve the keyboard focus problem.
