hi&thanks for this great patch!

i got pretty frustrated to see that my old p4 pc running sketchup on winxp easily outperforms my macbook due to the mentioned freezes...
disabling fast feedback only did not help. if i disable hw acceleration, the freezes vanish. but of course you get visibly better performance using the patch. (btw, rotating large structures without hw accel on the mac looks about as "smooth" as with hw accel on the mentioned pc with geforce fx 5200 go)

running SketchUp 7 (7.0.10938) on Mac OS X 10.5.8

i wonder if 10.6 works any better - according to http://developer.apple.com/graphicsimaging/opengl/capabilities/ opengl implementetion has been worked on since 10.5.8 (version 2.0 for gma x3100 and 1.4 for gma 950 instead of 1.2 for both in leopard).
