Since updating to Mavericks, I experience cursor placement trouble when I compose emails while replying/forwarding. It all works as long as I am writing consecutively, but once I try to position my cursor somewhere in the middle of the already-written text, the position is several spaces off. It becomes very clear when spell-check tries to underline a misspelled word (it's always one or two words to the left of the actual word). It's very confusing. I read that people with Google Apps have the same problem, but I am not using that. It's a regular mail-server-based account on my personal website (pop). Any help is very much appreciated, since it drives me nuts. Thank you!
