hmmm....
As a Test:
1) Try your Save to Clipboard (That error should show)
2) Try to do a CTRL+V somewhere else (say in gimp or wherever)
3) Try your Save to Clipboard again --> Does the error occur again?
Otherwise i'm out of ideas

because main file png.pas has only 28 lines
This seems to indicate that you are not writing a standard LCL GUI application. In this case you probably did not have the unit InterfaceBase (or Interfaces?) in the uses clause and thus did not initialize the widgetset-based access to the clipboard.

As I assumed, there was something wrong in the kind in which I started my program. To find out, what I must change, I created a new Topic and a small demo project:
https://forum.lazarus.freepascal.org/index.php/topic,69574.0.html
I close this Topic now. Thanks a lot to wp and Zvoni for your help.
