Hello,
when I take a screen shot, add some objects and hit {Ctrl}+{S} to save, then I see in the file tab also the .objects file for the saved screen shot.
See attached screen shot ScreenshotCaptor.png.
When I press {F5} then the .objects file dis-appears.
This problem occurs often.
If I adjust 3 screen shots, I see also 3 .objects files.
Greetings
OLLI
