When I responded to a forum post, I noticed I made a mistake in my post after posting it. So I hit the Edit button, corrected the mistake, and submitted it. Then the edited post appeared as a new post, and my first post was still there, no change made to it. But I know this is not how editing your own post should work... maybe that happens in a certain condition?
Editing now... does this appear in the original post?
2nd edit. Okay so editing works just fine. I'm pretty sure I hit the Edit when I encountered this problem... hmm weird...
