Display Lists

I am running my openGL primitives through a display list and now my program is much faster. I actually will have to change the movement algorithms to slow some of the objects down. However I did get the following error after creating many many shapes.

2009-02-18 18:12:50.225 openFrameworksDebug[2294:10b] *** -[GLUTView wantsLayer]: unrecognized selector sent to instance 0x47c050
2009-02-18 18:12:50.227 openFrameworksDebug[2294:10b] GLUT Fatal Error: internal error: NSInvalidArgumentException, reason: *** -[GLUTView wantsLayer]: unrecognized selector sent to instance 0x47c050

Looking into whatever this is.
