Soverywrite, it sounds like exactly what I’ve been reporting. While I regret that you are experiencing the trouble I am, on some level it is nice to know that I am not alone (meaning, it’s not just me or my machine). On my other related post ([url]Auto-correction substitution - curious behavior]), MM replied last night with the following:
I did respond that I’ve tried to add spaces before and after words in the list (trying to force it to find whole words only) but it did not help. For now, I’ve just had to remove words like “ot,” “hte,” “od,” “id,” etcetera from the list and catch them manuall in a spell check.
