Biggest annoyance with this software - backspace is, apparently, something that I alone exercise. If you type an incorrect letter, it simply doesn't advance the cursor rather than advancing the cursor and marking the letter as incorrect. Since I am already a pretty good touch-typist, I routinely KNOW I have hit an incorrect key, hit backspace, and correct it and progress with the word.<p>However, very often I will do something like spelling "icnorrect" from feeling, then hitting backspace exactly eight times and re-type "ncorrect"... which is simply not supported by this software.
