I unloaded all the extensions until I was left with the 3 for SpellBound. Nothing changed until I unloaded the 3 extensions involved with the spell checker. Now it's back to normal.

Weird.

I can edit my toolbars again too.

Weird.

[edit:] On reinstalling the extensions above: Toolbar Buttons 0.2.5.3 is incompatible with FiFo 1.5.0.5. The other extensions listed above work, but you have to get the right Spellbound packages. See the Site Search for a post of mine with pointers. The wide bottom bar and other artifacts are gone. Woot!

Cheers,
Scott.
(Who now gets to reinstall the extensions and see if the problems come back...)
