Marc, you are definitely getting the idea totally wrong. We are talking
about the user pressing the Cancel button in a save-plugin dialog. You
know, the kind of dialog that asks for a comment, or compression level or
whatever before anything actually happens. As it is know, the save plugins
return with STATUS_EXECUTION_ERROR if this happens and the core pops up a
warning message as a result. The plugins can however not return
STATUS_SUCCESS since if they would the image would be marked as clean
even though is was not saved.
Cancelling a running plug-in from the core is another thing and it is of
course fine to pop up a message saying "Save failed" in that case.
Salut, Sven
