Glad I noticed this thread - this issue was bugging me for a while, and then 'magically' disappeared (or at least I haven't seen it again for a bit). I couldn't find a rhyme or reason to explain "what I was doing wrong". I hadn't supposed it was related to an OS bug, figured it must be something app-specific. But looking back I'm fairly certain the bug disappeared right around the time I probably installed the latest system update on my android phone.
