Why Doesn't This Python Program Work?

[toml_12953]

I've found out that, in the latest Betas, set_cartesian has no effect and the cartesian versions of the graphics commands don't work. This is both in the Python app and a PPL wrapper. My code worked perfectly before the Beta but now I'll have to wait for more fixes. This is a fairly major issue. It's very handy to define your own coordinates rather than have to calculate pixel positions on your own.
