Backspace, Home, Arrow keys (etc) don't work in SQL2K5 SSMS

When I edit a sql script in SQL2K% SSMS, the backspace, home, arrow keys (and several others) outright do not work.

I have uninstalled and installed SQL2K5 sever times for a resolution to this problem.

What is unique about this installation is that I have a SQL2K instance running on the same machine. I need to support both versions of SQL2K and SQL2K5.

Also, In the tollbar thare are 4 repitions of each menu item (4 File, 4 Edit, 4 View).

I have tried several tool options to no avail. I have deleted the vsk file (no help).

I am running W2K Pro (SP4).

Did anyone else have problems with SSMS after a SQL2K5 side-by-side install with SQL2K?

Can anyone provide a cluse on what to do next?

TIA!!!
