Just upgraded a test site to 2.1 from 2.0.5 - nice and quick, just the usual process.
Everything works fine, apart from the spell checker. I can click the little drop-down and see that English is ticked.
I am using Firefox 188.8.131.52 on an Intel Mac running OSX 10.4.8
When I click on the spell checker icon, the editor fades out and the spell checker progress indicator comes up, but it always says 'no misspellings found'.
99% of my clients use Internet Explorer on Windows, so as long as it functions in that I guess it's not too bad - but I'd really like the spell checker to work for me too!
Has anyone got any other experience of 2.1 spell checker on OSX?
