I just finished the upgrade to 2.10 and everything appears to have gone great...except that the spellchecker built into WP doesn't work. After making some very obvious mistakes, I click the ABC button and it says "no misspellings found."
Secondly, the built in FireFox doesn't work on the visual editor unless I right click and select "spell check this field." Does anyone know how to turn it on permanently for the visual WP editor?
