I am using GraphCalc 4.0.1 but this also applies to the latest version.
I am Eric Hutchinson, at eric.hutchinson@...
I am running GraphCalc on Window XP and on Windows 7 (error happening on each operation system)
The error is recreatable for my specific function I want to graph.
The error is occuring when I graph y1 = 2x^4+x^3-35x^2-113x+65. The graph is supposed to cross at x = 1/2 and x = 5, but when you have the standard 10 by 10 viewing window, it only goes through 1/2. However if you change the the viewing window to something else, the graph then it does show the graph going through x = 5. It tried changing the viewing window to xmin = -1 and xmax at x=6 and the graph did go through x=5.
