For some reason, the IE Spell Check button is stuck in the toolbar even though it's not in the toolbar at all in my settings. I have tried clearing the browser cache. I'm not sure why a button would just get randomly stuck.
Here are supporting screen shots:
Visual Editor toolbar (what shows): http://d.pr/i/ubkv
TinyMCE Advanced settings (what I want to show): http://d.pr/i/A8og
Any ideas? Thank you.
