This has been happening for a while... if I click on a photo in a thread to make it full screen, then click on it again to swipe it away, the app crashes. It seems to happen if I linger on the photo for more than a millisecond! Particularly annoying as I read lots of threads in active and can't always find them again, having failed to notice the topic (I admit that bit is user error 
)
I'm on the app on an iPad.
Anyone else?
