Using spell check on 1 document - no spelling mistakes, uncapitalised words etc are picked up.
I have checked that languages are set (ie not on 'no language') and spell check is to pick up all mistakes, along with dynamic spelling turned on still shows no errors...even when a forced mistake is typed.
No other documents have this problem.
Also tested on 3 machines and all have the same issue for this 1 document.
Are there any document overrides I have missed that could be causing this?
Common alternate spellings, like US/UK differences generally slip past Spell Check, and a User dictionary might include your misspelled words.
