when writing text in a Gmail sometimes I must have accidently pressed some button to cause this glitch.
When I move my cursor to a mis-spelled word to correct it, instead of the cursor positioning in between 2 letters it highlights one of the letters. If I then delete that letter the highlight goes to the following letter so that when I add the correct letter the following letter is deleted and so on. If I then add that letter the next letter is deleted! If the correction is needed in the middle of a long email then Oh!
I can continue OK from the end of the text but I have to leave that glitch behind unless I retype all from that point and make sure I don't make any more mistakes.
In this text here there is no problem so it appears only in Gmail. If I bring up a new Compose the glitch remains. I'm using Win 7 but it has happened before in XP. I've tried pressing all the function buttons (Ctrl, Alt, Esc etc.) in combinations to no avail.
Perhaps only a reboot fixes it but that's a long way round. Any help please.
