[Visualpython-users] 128 point limit in curve?

Hi all,
Newbie here.

I have just downloaded and run up vpython 2002-07-22 and am now getting a 128 point limit on the curve class. Any more points and it crashes. 
When I was running the vpython for python 2.1 (cant remember the vpython number) it definitely did not crash.

Nice product. Using it for teaching my kids physics.

TIA
