Hi Jan,
I don't know if this will help, but what I usually do when I'm at a spot it always wants to crash is first not click on close, then drag the box over out of the way...off the screen with just enough showing to pull it back when I'm finished and READY to close. And of course save, save SAVE after that.
It's only a band-aid fix, but it works for me! Hope that helps.
