Hello Tomaž, Svetlana, I hope that my advice about checking the default applications and types helped you out. For Tomaž it is just a matter of things using right. For Svetlana, installation and plists need to be checked, since it is strange.
However, giving the advice to "show" what kind of documents an applications opens in the inspector made me look at the code again. Since ever, GWorkspace displayed "RTFD" but not the classic "RTF"... the same goes for Grr where some kinds where not displayed. Furthermore, maybe you noticed, for certain application no types&icons were displayed at all! I think the code was not right, trying to de-duplicate extensions and icons. It took me two attempts, but I rewrote it so that all known extensions are displayed and if an Icon is supplied, it is displayed, otherwise not, but the extension is still listed. This is much more user-friendly: it gives the complete information about the App capabilities. Try & Enjoy. Riccardo
