I don't know how this happens, but sometimes when I type a reply on here or type on an email or something, this happens. I'm guessing this feature is universal. I type something, then if I have to correct it and use backspace, then type again, whatever new words that I type overwrites whatever is already on there, when it should just PUSH whatever's on there to the right. Like if I type in a sentence, then put the cursor in the middle of the sentence and start typing, it should just push along whatever is on the right, but instead, it just stays there while whatever I'm typing "overwrites" the existing words. Not sure if you guys get what I'm trying to say. I can't seem to replicate it. It's very annoying when it happens when I'm writing an email at work and it does this.
