So thanks for all the neat tips and such. I've been playing with them and see how they can be handy. I've read about the timestep stuff before, but hadn't thought about the integers thing.

However, I still have the same issue as I have had the past few posts. The script editor does not seem to be recognizing the center_x command for either of the panels I am playing with (center_y works fine). I'm not super familiar with computers, but I do recall an earlier issue I had with certain lines not being read. After switching the order of independent strings of code (seemingly irrelevant) it started working but such attempts with this line seem fruitless. Could it be a syntax issue or a bad install of the SED script editor?
