Scrolling via mouse wheel moves tiles off screen.

Scrolling through items using the mouse wheel, I can scroll the tiles completely off the screen.

This is related but if you want we can create a new issue:

When using a touch screen and you drag left/right it seems to go by page (appears to be about a screen width on my tablet) lets say 10 posters. If you have 22 posters then when you drag on the second "page" (11-20) to go to the last two posters you end up with a black screen (you go past the last posters).

I actually think that it's paging more then what is visible on the screen on my tablet's resolution (1280x800) which makes the whole process even worse.
