Cursor jumps elsewhere randomly when answering emails
When I open an email and then reply to it I start typing and suddenly the cursor has jumped elsewhere in the email (often into the email I am responding to) and I look up and see that I am typing elsewhere. Have to delete the letters/words and reposition the cursor where it should be. Sometimes it skips again immediately after typing one letter other times after a few letters. It's driving me mad. I have done a complete reset as instructed by Apple but that did not solve it. I cannot work this way. It is not fit for purpose at the moment.
