If you open a read-only file (e.g. something installed in yr linux class lib), then edit it, when you try and quit you get the "Unsaved documents" dialog. All fine so far. However, if you press the default "Save" button nothing happens - the dialog momentarily disappears and reappears, since of course it has failed to save.
In fact, I realise now that this happens if you do ordinary File>Save too. Nothing happens, and the file stays in unsaved state.
What it should do (IMHO) is trigger a Save-as dialog for the unwriteable files.
