Can we have it *not* throw up an obnoxious invisible box while it's loading?

The number of time's I've posted something and then immediately lost all of it because that loading thing never went away and I had to reload the page... Way, way too many. There needs to be a button that says, "Yeah, nevermind, fuck that, stop trying to post so I can fiddle with the settings."

Also, is it down for anyone else?
