Happens in Firefox and chrome. Sony Xperia T. Android 4.3. The touch screen keypad disappears while I'm typing a post. Seems to happen when the forum saves a draft of the post. Also seems to be linked to browser cache, as emptying that in chrome fixes it for a while. Tried switching from the forum custom skin back to default. Didn't help. Am making this post long to try and make it happen here. Doesn't seem to be happening here. Ideas?
