The first time no, the viewer section says "yap" for DVI and is empty for all other File formats. After a restart (without reconfiguring), the viewer edit box contains auto for all format.
This is weird, and I have to try it myself. What you are saying is that lyxrc.default is generated correctly, but is not *loaded* at the first time. If this is true, this should have nothing to do with my patch, but the way multiple rc files are handled. Cheers, Bo
