Preview can no longer autosave
Hi there,
I am having problems saving edits in Preview. This only just started happening today for some reason. After I've edited a file on Preview, when I try to close the file down the message comes up saying it "could not be autosaved. Your changes will not be saved until the problem is resolved". I should add that there's no option to "save as" instead.
Any help would be appreciated!
