I'll let the native English speakers decide if "does not operate on" is better than "cannot manipulate", but otherwise I'm ready to add the tests for the layer masks or channels.
"does not operate on" seems like a developer's or mathematician's comment, not language for the end-user who thinks he is using an Image Manipulation Program.
"cannot manipulate" reads much better for me , native english further back than the Queen (which ain't that far actually. Their family name was Sachsen-Coburg-Gotha until being german became uncool around the early part of the last century and they decided to borrow the name of a castle. ;) ). _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
