Every time I type the word "daylily" the software on my Mac immediately changes it to "day lily" -- and also "tet" keeps changing to "get" and there are a couple of others -- so just before I hit the Finished button I always have to proof my message and change everything back to the way I want it, and still sometimes the software makes those changes again on something at the last second. But I've really gotten used to proofing before sending now, so usually I catch them -- or I can go back and Edit to make the changes once again. And my IPad does the same thing.
