Vista - Yamaha mLAN drivers and tools

Posted this question on the mLAN forums also but they are not an adventurous
group, so I'll try here also.

Vista RC 2 x64. The XP x64 drivers appear to install correctly if you
disable driver enforcement, but the Tools (software interface) doesn't seem
to work correctly. The connections for MIDI and ASIO inputs\outputs are
garbled and it's difficult to tell if the Auto Connector worked correctly in
the Graphic Patch Bay. In List View when I click on a connection it just
gives me the Windows error sound so again it's difficult to tell if the
connection shown is actually connected.

Anybody else out there in Vista world have any success in this area?

Yamaha is working on Vista drivers but I'm sure it will be a few more months
before they come out. This is one of the last pieces that has me rebooting
into XP x64.

Thanks.
