Try it. Open any WCB in WCM exchange, and type a message in the contact box. When typing a message longer than the available space, the box will jump to the top of the message, then back down to the bit you're typing.
Edit: Also, the amount of allowed characters is far too low. I can't formulate a proper request for licensing and pricing information in there. Not very good, if you want to sell stuff though that.
Edit 2: Also, the message you get when sending a message is odd:
"Your e-mail has been sent to the concerned developer."
I like how the developer is concerned, but I don't think that is the proper word to be using in that case. You could rephrase it as 'Your message (as it's not an e-mail, but a message you're sending, technically speaking) has been sent to the developer', or 'the publisher', or 'the contact(s)'.
Synonyms for Concerned include:
uneasy
solicitous
disturbed
uptight
impl icated
interested
nervous
Just so.
