[SciPy-user] problem with the determinant of matrix

Could this be the issue that the SciPy build on the website was built 
with SSE2 support and you don't have SSE2? Do you have an older 
processor (other than Intel Pentium 3 or AMD something-or-other)? Not 
using Windows much, I don't keep track of the details, but there 
historically has been the occasional issue along these lines, and I'm 
not sure it's been addressed.
