I'm pasting this reply in hopes we can a solution. So far the only issues I have that I can reproduce are:
This version of WP Super Edit has been tested on WordPress 3.1 and I may have introduced some issues affecting older versions of WordPress. If so you may want to check the "Other Versions" and downgrade to an older version.
I'm also interested to see if this is a PHP4 issue.
I was finally able to reproduce an issue causing the editor to malfunction on older websites using WP Super Edit.
I couple versions ago I moved the "Custom CSS Classes" and "Super Emoticons" from being just "TinyMCE" plugins to being separate "WordPress Plugins". This was done because those two (and other personal ones) have functionality that requires more access to the WordPress internals, so they have to be activated as separate WordPress plugins.
This fixed an issue dealing with callback functions that I shouldn't have been doing in the first place. Unfortunately it looks like it broke some sites that may have had these active for a long time.
The easiest solution is to reload WP Super Edit.
Unfortunately this will clear out all settings for the buttons and plugins that you may have had previously. You have my sincerest apologies.
If you are brave, before you do any of this do a backup of the wp_super_edit_users table in your database. That table stores the actual button configurations, so you may be able to replace that table AFTER the reinstall and get some of your user's configurations working as before. I haven't tested this, but it should work.
