There is no button, its in the html like below...
"color: #000000; font-family: Verdana, Helvetica, Arial, sans-serif; font-size: 75%; background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: #ffffff; min-height: 100%; position: relative; text-align: left; padding: 0px; margin: 0px;"><p style="padding: 0.4em; margin: 0px;">Did you copy and paste from a text editor or different window? It does that sometimes. Click the html button, where its says 75% in the text change it to 100%
Anything like that in the html? (on the little post, it wont show any html on the normal ones)
