Hi Bruce: I KNOW exactly how you feel. You're right that the 'Main' button automatically goes back to the #1 (A) position when you change registrations with the 'freeze' button off.
What I have to do when changing registrations (and wanting to change the left part too) is to press the appropriate 'Main" variation button immediately after pressing a new registration button.
It certainly is a BIG PAIN in the a*s, but I use a MFC10 foot controler to trigger the Main buttons, so it makes it at least a 'little' bit easier.
The problem at hand is actually a Yamaha acknowledged bug which occurs only on certain earlier PSR2000's. Newer released 2000's include a newer OS which apparently has corected the problem. See Carlos Rodrigues post on the same thread:
http://www.synthzone.com/ubbs/Forum37/HTML/002610.html I, and I'm sure many others here as well, am 'anxiously waiting' for an OS update to be made available from Yamaha for download. So far, not a word from Yamaha. Anyone else hear anything yet?
