[Visualpython-users] Odd crashes in Win98

[Gary P. <pa...@in...>]

I've installed vpython (VPython-2002-12-12) on my Windows98 system.  I've
got Numeric 22.0 and python 2.2.2.  I'm exploring it for the first time.
I've tried VPython-2002-10-12, but that doesn't work at all.  I think I read
that the problem there is incompatibility with Numeric 22.0.

I'm getting the craziest kind of failure.  Sometime after running vpython
apps succesfully a few times, and the number of times can vary from zero to
about 10,  a window will pop up telling me that the program has performed an
illegal operation and will be shut down.  There is a "close" button on the
window, but it closes neither the window itself, or any of the windows being
used by vpython.  There is no way to close that dialog window.  In fact, if
I simply move the window out of the way, I can carry on in every respect.
python runs, vpython works, all other Windows apps seem to work.

However:  ctrl-alt-delete does not bring up the Close Program dialog.    If
I continue using vpython, the system seems to eventually freeze, and with an
inoperable ctrl-alt-del, I have no option but to cycle power.  If I close
all the python windows (except, of course, the error window which will not
close)  things seem ok, but eventually other apps start behaving strangely,
and I have to reboot, which I can do in normal fashion from the Start
button.  Something's gotten polluted.

I suppose I could try VPython-2002-10-12 and Numeric 20.3, but shouldn't my
set up work?

any advice?
thanks,
