I'm pretty sure there isn't a setting that controls that, or a way to make it stop other than hoping a service pack fixes it. There have been other instances in the last few years. If I remember right it would happen with SW2012 when opening files by clicking on them in Windows Explorer, but not when opening them by dragging. It happens to me now with SW2015 when using the Replace Components command in assemblies.
It also happens when I replace components as well. Like I said it is not a huge issue, but it is annoying to have to keep resizing the window.
