I saw a posting that mentioned directx 5.0b & someone asked how to get it.
As promised, I looked into this. The DirectX team will be posting an update
(it isn't officially called 5.0b - just 5.0) for download from the
Microsoft site within the next few days. The changes in the newer version
are to do a better job of selecting the correct sound driver when installing
directx. There are no new directx drivers in the distribution, so no need to
bother getting it if you already have directx 5 unless you are having some
problems with your sound card...
