Drag and drop an image from PM+ to an Image Editor shortcut on the iMac dock, and the action produces an "image cannot be opened.." message from the app. The drag action from PM+ is including sidecar files -- both .xmp and .on1 files in one case, according to the editing app. Is there a way these sidecars can be excluded?
