MS SQL 2000 support

Hi I'm a new user and am so far enjoying using the program. It connects to MS SQL 2000 just fine and can do some basic things. But on more advanced features it fails, because it seems to assume a lot of sys.* tables should exist when they won't in that version. I can't see and modify the source of views, procs, etc. Is there an option I should set to tell it that I'm using SQL 2000 and so it should use different system tables? Thanks DC
