Yep, now that you mention it i think the conversation window was open in background.. personally i would like the app to give me sms notification unless the converation window for that person is active but can see that might be hard to achieve and you may not want to. Tested this morn with missed call and then sms- sms notification clears the call one so it is working as you intended Haven't gone to next version yet but will later today and will feedback if anything changes
