[Plugin: BuddyPress Activity Plus] Video and Link URL Text box overflows it's container

Video and Link URL Text box overflows it’s container on every theme I’ve tried it on. I’ve tried countless times to figure out what css controls this but have had no success.

I’ve tried editing the interface thus:

#bpfb_video_url.changed, #bpfb_link_preview_url.changed {
	color: #333;
	font-style: normal;
	width: 400px;
}

I’ve tried editing the post form thus:

<textarea name="whats-new" id="whats-new" cols="28" rows="8"><?php if ( isset( $_GET['r'] ) ) : ?>@<?php echo esc_attr( $_GET['r'] ); ?> <?php endif; ?></textarea>

I’ve tried custom css thus:

input#bpfb_video_url.changed, #bpfb_link_preview_url.changed {
width: 360px;
}

I’ve tried percentages and nothing seems to effect it in the least.

here are screenshots of what I’m talking about:

It also kind of annoys me that the helper text doesn’t disappear. I’ve teetered on the edge of buying into your dev program but this plugin seems so half-baked that frankly I just don’t trust that there is much attention to detail.

I mean this guy has been begging for nearly a year for someone to show what mysterious css voodoo controls things like this but no one seems able to accurately answer.

Anyone out there have the answers we’re looking for??
