Crash Report, Resizing a mystery square

Version 1.9.7 on Windows 10.

What happened:

I did an Edit/Insert Image Linked to file with this image:


I split the edit window in two (horizontal split)
I noticed that in the lower window, in addition to the image, there was a rectangle with a tiny square in its lower right corner. I’d never seen that before.
Curious, I clicked on the tiny square, and resized the rectangle.
In an instant Scrivener was gone. Crashed.

Hope that helps!

Many were facing the issue the week you posted did thread, but I tried later and it was working fine. Do recheck once now.
