MemberAccessException during un-DropShadow of Ellipse

I got an exception while using the Image Editor of Greenshot.

Steps taken before the screenshot:

  1. took a "region" screenshot

  2. added a rectangle (with drop shadow)

  3. added an ellipse (with drop shadow)

  4. let that window sit for several minutes during an interruption

  5. took another "region" screenshot (opening a 2nd image editor window)

  6. quit the 2nd image editor window

  7. back in the 1st image editor window, selected the ellipse

  8. clicked icon for drop shadow to turn it off

  9. EXCEPTION THROWN HERE

  10. copied modal window with exception text

  11. clicked icon for "copy image to clipboard"

  12. pasted into Outlook email just fine 🙂
