Sometimes when I edit something, what I type will overlap what has already been typed. Then I have to redo everything after what I edited. What causes this and how can I stop it? -CE5

Ex.
Strong Bad goes to Cheat's house -> Strong Bad goes to The t's house as opposed to
Strong Bad goes to Cheat's house -> Strong Bad goes to The Cheat's house

I think thats not the wiki's fault because that happens sometimes when you are not editing. i think it has something to do with the alt button.

That'll be because of the Insert key. If you've accidentally pressed it, it'll cause anything you type to delete the text in front of it. To stop it, just press it again. --Upsilon

I have the EXACT same problem! Thanks for the info, Upsilon!
