can't get rid of a video

[casper50]

I've got a problem posting in a post that I've already posted in. (say that 3 times fast).  The "new post window" at the bottom of the page will already have whatever I've previously posted.  I just highlight and delete words but how do I get rid of a video that is always in the new post window?
