Squishing bugs

So, squished another bug, for my non-existent git followers.

Also, determined that using scheme for my program of insanity is not going to be the easiest thing in the world, not to mention I haven’t done any speed tests (now I check the computer language shootout…) and scheme is a bit slow for intensive computation (not that it really matters when you have cores and gigahertz to spare). Plus, getting scheme to play with wxwindows seems like it would be a pain. On the other hand, writing C wouldn’t be a whole lot of fun, neither. Ah, conundrums…

I need a name for a differential equation explorer.
