Today, for the first time ever, I am getting this magenta rectangle on-screen. I can use the handles to resize it, but I want to delete it!
It is parallel to the screen. I can rotate a part (behind it) but the rectangle stays fixed.
It shows up when I open an existing (or create new) part or assembly, but not drawings. SW2015 SP5.
I also have SW2014 & SW2016 installed and they are OK.
So where did it come from and how do I get rid of it?
