Yes.

Yes, the animations seem to be working fine ... (ball bouncing, etc)

The first time I press ctrl-c, I get this:

^CTraceback (most recent call last):
  File "bounce.py", line 10, in ?
    rate(100)
  File "/usr/local/lib/python2.3/site-packages/visual/__init__.py", line 34, 
in __call__
    return apply(self.constr, args, kw)
KeyboardInterrupt

Then on the second press of ctrl-c:

^CError in sys.exitfunc:
Traceback (most recent call last):
  File "/usr/local/lib/python2.3/atexit.py", line 20, in _run_exitfuncs
    func(*targs, **kargs)
  File "/usr/local/lib/python2.3/site-packages/visual/__init__.py", line 67, 
in __waitclose
    while not cvisual.allclosed(): time.sleep(0.05)
KeyboardInterrupt
Xlib: unexpected async reply (sequence 0x1e66)!

I tried again with the newer version, using gcc-3.3,
but I am not sure that will work with a
libboost_python that is built with gcc2.95 ...

I had to move cvisualmodule.1 to cvisualmodule.so
and I am getting this error:


>>>import cvisualmodule
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: /usr/local/lib/python2.3/site-packages/cvisualmodule.so: 
Undefined symbol "_ZTVN10__cxxabiv120__si_class_type_infoE"


Thank you for your time.
