Unselected function's graph appears (aka The Case of the Ghost Curve)
Another graphing bug: this one's 2D. I'm getting a sort of "ghost" curve when working with graphs. In the picture, you see a blue parabola. It's the graph of the lowest equation in the algebra window. However, it's not selected, and it's correct color is red.
When I select that function to appear, both the red (which should be there) and the blue curves overlap.
The only way I've found to remove one of these "ghosts" is to quit and reopen the file. (The "ghosts" have showed up in other shades as well: gray and green.)
