Thanks for your help about where to turn on Spell Check :)
Here's the test... if you look at the source code, it appears that spell check does work in a "text area," field, but does not work in a "text input" box.
So if you're only testing this in a text area, it appears to be OK...
But, here's the rub. And this is the weirdest thing. When I cleared my Autofill list as mentioned by jfew, the spelling started working in the text area fields (which had previously stopped working).
As for bug reports. Yes I file them. But I like to make sure that it's really a bug and not operator error first.
