Hi David,

Although the processor is Intel Duo Core E6700, which supports x86-64,
I am only using 32-bit Windows XP. I am not using my own BLAS. I am
simply using the pre-compiled binary. I installed 1.04 over the old
1.031. I don't know if it is caused by some files that are left
behind.

Thanks,
Geoffrey
