title: Notepad++ replacing letters when I put anything infront
body: <p>This is a little hard to explain, but if I go back on some text and press space, it doesn't move the whole text it just replace the character in front of the place where I want to put space with a space. How do i stop it doing this?</p>
  <p>This is basically making it almost impossible to fix code.</p>
  <p>I have spent a little while fiddiling around in notepad++ but nothing seems to be doing anything useful, I am pretty sure its recently become like this, but I haven't used it in a couple of months.</p>
  <p>PS. it is not just if I put a space, but any letter or number.</p>
  <p>Below is a link to a youtube video that showcases my problem:</p>
