Well, now that the August 2005 DirectX SDK is released, as well as the IE7 beta being made available to MSDN subscribers, I'm guessing it's only a matter of oh, say, minutes before somebody discovers this: If you try to install a DirectX sample using the DirectX Sample Browser, and you have IE7 installed, it will fail (basically it says, "Could not locate folder...").  The only workaround at the moment, sadly, is to uninstall IE7.

I'll post a new update to this blog, as well as to the MSDN Game Development Forums, once this changes.
