Gordon Evans 2 years ago I have a similar problem to this vimeo.com/forums/help/topic:113448 but on my BlackBerry 10 Z10 browser. Vimeo videos open fullscreen in the native player and if I click the back button or exit fullscreen I'm left with a 1 pixel video (still playing usually). I read the aforementioned topic which said it was a problem with android os (and possibly BB OS) but I noticed something else. If I go to the vimeo mobile site all the videos on the homepage work just fine. I click play, the video opens in the native player, I click back and I'm left with the page looking just like I left it. No black holes! If I look at the video (still on the mobile site) but going through the authors page it does not work as expected. When I click the back button, I'm left with a black hole (ie no thumbnail image of the video). What gives? Why is this one section of the Vimeo mobile site different than others? Different Vimeo player?
