Haha. Maybe you can help me. Every once in awhile, and that was one occasion, when I try to quote somebody a couple of times, so I can break up the post and respond to each sentence specifically, @iacas style, and there is no space between the two boxes, it only lets me put my cursor immediately in front of "quote." When I hit backspace to try and un-indent, it puts my cursor IN the previous quote box. Even after I hit enter a few times to manually create some space, it still won't let me get rid of the indentations.
Sorry bro, it's like Aimpoint, I could explain it to you but then I'd have to kill you.
There are probably easier ways, but what I do is copy/paste the quote as many times as I want to break it up and then write my comments between each box. Once I'm done I go back and edit each box to just the parts I'm commenting on. It's not always necessary as sometimes the editor behaves but when it gets all squirrelly I find this is a good work around.
