When opening a file and performing an export and no other operation. The export is logged as a change in the history to the original. This is not what the export function does. It uses the original as a source to create a new file in a different or same format but different name. This should not be taken as a change to the original. Since AP logs this as a change to close the original requires an extra step to save the change that didn't happen or exit without saving the non-existent change.
