Vista (5536) doesn't work with Groove 2007 beta?

Installed the pre-RC1 and Office Beta 2 last week. All works really well, and
besides all the negativity out there on newsgroups and in the press, I think
Vista and Office are looking great. I own a Mac as well, and honestly don't
see what all the OS X fuss is all about. I've had apps crash on Mac as
well... Happens...

Anyway... my question... has anyone tried running Groove on Vista? I have
serious rendering issues, where the folder icons within Groove seem to have
the wrong bitmap, also the calendering tool doesn't show appointments and
even crashes Groove when trying to add new appointments.

Just wondering if I'm alone or whether this is a known issue that's being
worked on.

Oh, BTW, if you haven't tried Groove, and you work in project groups or
teams: GET GROOVE!

Thanks,

JB
