The share button doesn't seem to work anymore, since the last update; running iOS 5 on an iPad 2. This is one of the buttons you get when you tap the the blue down arrow in a post's header. Normally this button opens an email editor with the thread title as the subject and it's link in the body. When I tap the button the action (box/arrow) icon at the top right of the screen goes dim and you can not longer scroll the screen. Tapping anywhere on the screen returns the app to normal. Once I got a connection error that may or may not be related; it was only once. Otherwise there is nothing at all happens. I've tried the usual fixes. Logging in and out. Restart/reset the iPad. Delete and re-download the app. I didn't see this one mentioned in other threads and figured there might be a slim chance you didn't notice it. Thanks for your hard work on the app. Edit: It works on the iPhone 4, btw. Just tested .
