Hello! I'm using Ubuntu, and therefore Wine 1.0.1. There's a freeware math tool called GrafEq (http://www.peda.com/grafeq/gallery/rogue.html). It draws graphs of implicit fiunctions. (There are millions of softwares that draw graphs of explicit functions, but implicit functions ("relationships", to be exact) are a different story.) So... GrafEq doesn't quite run for me under Wine. I see nothing inside its window. Could anybody please try to run GrafEq on his sytem and tell me if he (or she) had a success? Here's where to download it: http://www.peda.com/download/
