By "this", do you mean 64-bit Windows 7, or Python 2.7?

Thanks.  Though I thought that the --find-jvm-dll switch only worked if
it was explicitly specified, which I wasn't doing.  So while that's one
Python 2.7 issue, I don't think that's the problem I was seeing, right?

I'm going to go back to 32-bit XP, and get things working with Python
2.7 on that platform.  Once I have that, I'll go back to 64-bit Windows 7.
