Delete, backspace, and arrow keys activate twice

[Alduins Khajiit]

Whenever I use the arrow, backspace, or delete keys, it's as if the key was pressed twice. i.e. if backspace is pressed, two characters are deleted, if the left arrow key is pressed, the cursor moves two spaces, etc

how do I fix?

You test with another keyboard to see if the problem is with your keyboard.

Testing with another keyboard is generally the best suggestion, but if you don't have one available or just want to try something else, visit the following link;

You state this only happens with arrow, backspace or delete keys which is odd.
