Can Infusion check my spelling?
Infusion does come complete with a spell check program built into it. BUT it will only work on Proper case words. It will not pick up incorrect spelling if the words are all in upper case.
See the comparison below:
Unfortunately the ability to add words to the dictionary is not currently working - see ticket 13272
See Spell Check not Working after Upgrade to 8.516 if your spell check is not working.
