Quick reply box sized-up covers preview and send buttons

Hello,

I have followed the tuto found here : https://help.forumotion.com/t145837-how-to-change-the-default-quick-reply-box-size?highlight=chatbox+send+area+size

to size up the quick-reply box, unfortunately it covers the preview and send buttons now as seen in this screenshot : http://hpics.li/108499a

this is not a major issue but still is bothering ^^

thank you,

Ency

Please post a link to a topic that guests can see and use the quick reply editor.

Hmm... I have allowed guests to post reply here : http://siri.forumactif.org/t273-candidature-pierre_auco#2106
although when I logout I can't see the quick reply box. Is there a specific parameter to allow it ?
