After I've typed a word or two in Greek in Logos, the cursor starts jumping back to the position before the letter I've just typed. For example (in English), if I am trying to type 'letter', after I've typed 'lette', when I type the 'r' the cursor jumps back to before the second 'e' in the word. I have to then manually move the cursor back to after the 'r'. If I then decide to add an 's' to the word, the cursor jumps to the position before the 'r', and I have to manually move the cursor again. And so on. This effectively makes typing in Greek pointless!
