Spell check causes crash

[kb5cth]

Admin,

I have been experiencing odd spellcheck behavior recently and think it may be related to this change. When I mis-spell a word, it gets underlined in red (good). When I fix the word, the underline doesn't go away (Not good). Then, as I progress in my writing and a line of text appears below the mis-spelled word, another red line appears under the word below the originally mis-spelled word corresponding to the letters of the original word. If I make to a third line below the original, the same thing happens (confusing).

It isn't life threatening, simply annoying. But it does greatly devalue the spell-check function.

Any ideas?
