database diagrams in SQL 2000 + VS.NET 2005

I've recently upgraded to VS.NET 2005 (still using SQL Server 2000),
and I'm no longer able to edit database diagrams from with VS.NET as I
could with VS.NET 2003. Am I missing a setting somewhere, or is this no
longer
supported?
Thanks,
g.not sure about vs.NET 2005, but I know that you can't edit SQL server
2000 diagrams using sql server 2005 management studio, so I would
assume that VS 2005 has had to make a similar sacrifice in order to
provide the ability to edit the sql 2005 ones.
Cheers
Will|||Thanks. Good thing I kept VS2003 around, I guess!
