My computer is typing backwards. Really. I feel like I am in Bizzaro World. Now I can type this only by moving the cursor over after each letter.

I seem to remember that you,ve been using Firefox as your browser. The problem could be in the "add-ons". Also in the central top of you main page there's a " ABC Check", when you click on the arrow, there's an "autofix" that you can use.

Have you tried with Internet Explorer or Google Chrome browsers if the problem is there?

Thanks for the answer. I think that some thought I was kidding. I wasn't. I finally found out exactly what was happening, although I have no idea why it was happening nor of any solution but the tried and true "Turn it off. Turn it back on" fix.

What was causing the reverse lettering was that the computer was not moving the "space in which to type" forward after I typed each letter. Each letter appears to the left of the previously typed one. Of course it didn't happen all the time, which made it even worse.
