Mon Jan 29 18:49:07 2007 Jiri (George) Lebl <jirka@5z.com> * src/gnome-genius.c: do what we do on inside program runs, when we do "load and run" in terms of printout on the console Mon Jan 29 16:53:24 2007 Jiri (George) Lebl <jirka@5z.com> * src/gnome-genius.[ch]: add "remember" settings to the gui and by default don't remember precision and output settings as those are most likely temporary.
