Review for mms Auto Correct by Michael Pachta
Rated 4 out of 5 stars
Some people report that they cannot add new words because the respective buttons ("Add" and "Save List") are grayed out.
To activate these buttons just click on a random word inside the list of words that show misspelled words together with their respective corrections. You will notice that at least the "Delete" button, which was grayed out as well, becomes active now.
Now click into the "Replace" field, delete the word that has appeared there (it's the random word you clicked before) and enter your new misspelled word. Then click into the second field (labeled "With"), delete the word inside and enter your new correction. Both the "Add" button and the "Save List" button will be active now.
This is obviously a minor bug. I hope it will be fixed in the near future.
