A family of Microsoft relational database management systems designed for ease of use.
Ken,
I had the same trouble a few times after I installed the update. It seemed to happen when I made to many modifications to a data graphic. If I undid a couple of moves, saved the file, and then re-opened it, the problem cleared out. I have at least two updates since this one (KB3172437 and KB3178713) and I haven't had any further trouble yet.
