I just tried to save a file when I'd moved the directory that used to contain it, so LyX said "directory not found" or somesuch. Then, to my delight, it offered to save it renamed. Excellent. I clicked on "Save" and it then brought up the first error box again. Oops. However, when I clicked "OK" it brought up the "Save as" box, and all went well. So the feature works fine, but it is a little confusing to see the error box twice. I presume that most people don't see this feature very often (it's the first time I have); perhaps this is why there's a small problem? -- http://sc3d.org/rrt/ | certain, a. insufficiently analysed
