Bath swatter and Baby come to mind.
I have 8 accounts in OE6 and I have no problem accessing account details none are greyed out. I think that you have a problem with OE which is somehow blocking changes.
You could try running the Mail Protection Wizard again and remove protection to all accounts and see if that restores the settings, then run it again and select protect all accounts including future/new accounts (not sure of the wording WinXP doesn’t require the MPW).
