--- Comment #2 from Dr. Ing. Dieter Jurzitza dieter.jurzitza@t-online.de --- This is not true. I can say "duplicate" in one ltspice - pane within windows, mark the corresponding elements, switch to the other window pane (containing a different schematic) and paste the duplicated structure by Strg - V. Try on your own, this works flawlessly in windows. Attempting to do the very same action within wine does actually not work for me, (same version of ltspice, of course!). This is the reason why I opened this bug. I am using the latest version of ltspice as available from the main download site.
