It would appear that your system design and operational procedures need tidying up a bit. Why are you getting pop ups? Why, if you get pop ups, is there not a specific frequency for these pop ups to file on? Why are we discussing this after the operational implementation? This should have been covered during the early stages at "safety case" level prior to defining the operational requirements. Did your system have operational requirements or did you buy "off the shelf"?
Everything should start with an examination of the current system weaknesses and strengths since if you don't do this you have no future measure of comparison to ensure that you avoid such designed in problems. This is all basic stuff - or should be.
