This could also present an issue for Windows build, since 4.5 has
proved extremely slow on Windows but 4.4.3 works exactly as expected.
I don't know what else to try - I've debated going with VS 2005, but I
don't want to be stuck with having to use '05 indefinitely.  I'll keep
researching to see if there are any problems with 2008 that other
people have had as well, but I don't know what kind of difference it
would make.
