This is puzzling.
I wanted to open this old file, but when opened it only shows a black round cornered rectangle. Yet, in the preview before opening the file, it shows detailed work of more than just the black rectangle.
As far as I can tell, there are no hidden objects in the drawing. I've attached screen captures of what I am seeing during and after opening the file.
Does anyone know what's happened to this file? Can I retrieve it?
