LJ user experience grumble...

So, I've been having a very odd problem with LJ's new visual icon selection tool on commenting pages, and a cursory google search doesn't turn up anything specifically about this in the midst of the general (largely justifiable) complaints about the new commenting interface. Basically, about 7 out of 10 comments I make with the new interface end up posting with my default LJ userpic, instead of the one I've carefully selected in the whizzy visual selection tool. This is irritating. I mean, my default icon is generally fine. That's why it's my default. But the other ones would like a chance to play, too.

Is it just me? Is there a fix?
