Well, I checked now also on the laptop.....
Laptop: e17 (from Texstar - thus with kde base): link to program is added automatically to Menu>>Applications>>Wine>>Program
PC: e17 (from Smurfslover - gtk-based): no link available; however, I can add it to the panel, and to favorite programs (or key bindings or ....), because it's available there as application.... strange
Thanks for the package suggests Smurfslover, and thanks to Agust for suggesting them here!
