[Papervision3D] Why does Papervision hang when I view model from the side?

[Kevin Burke]

Thank you very much for your idea! I'm out of answers and I am still very 
unsatisfied because of this bug. I rounded the pitch as you suggested, but that 
did not fix the problem. However, I think you might be on to something because I 
traced the pitch & yaw of the camera and the 'hanging' behaviour happens when 
the yaw is ~0 and ~-90. When the Cloth modifier begins, the behaviour is more 
subdued, but as the modifier becomes more pronounced, so does the glitch. I just 
don't understand why the rendering stops only at these degrees of yaw? The movie 
seems to work fine when I orbit around the modified blanket from other degrees 
:-/ ?

could it be that the camera pitch should be rounded? maybe its going way to far 
after the decimal point.

I have a Papervision plane with an AS3DMod Cloth modifier applied to it. It runs 
well when viewed from the front and back, but it trips up for some reason when 
viewed from the side? http://www.kevinburkeportfolio.com/downstream/virgen.swf 
The orbit code has easing applied to it:

Any ideas?
