Attachmate EXTRA! Enterprise 2000 bugs?

I work in the IT department at U.S. Steel Corporate Headquarters in Pittsburgh PA. We started rolling out Windows 2000 Pro in the first Qtr. All has gone well until we upgraded our mainframe client from Attachmate Extra v6.5 to Enterprise 2K. My question consists of several parts.

First, has anyone else had problems installing Attachmate EXTRA! Enterprise 2000 on to Win2K?

Has anyone else had conflicts between Novell client 4.71 and Attachmate EXTRA! Enterprise 2000 (Novell is currently beta testing v4.8 SP3 for connectivity issues concerning Attachmate EXTRA! Enterprise 2000 among other issues)?

If you have had similar problems, what fixes have you tried and are they working?
