I'm not really sure if this qualifies as a bug or not (Probably not, but I'll put it here anyway). I was trying to use the word replacement to replace the letter I with another word.
For example:
I - to be replaced with - isn't
I then tried to replace i with I, so that it would still give me I when hitting the space bar.
i - to be replaced with I
It works so long as the I occurs mid-sentence, but not at the beginning of a sentence.
This doesn't seem to occur if I replace the letter A (or any other letter) with another word and do the same thing.
I was wondering if you could fix this. I like using the autotext to do single letter word replacements.
