I also have the plugin "Simple Select All Text Box" (http://wordpress.org/extend/plugins/simple-select-all-text-box/) installed and it works according to my settings (1 row/line tall, even though the code is longer than one line) when the contact form isn't on the page and also once the comment form is submitted (i.e. "message sent"). But at initial page load, the text box is several lines tall. Are these 2 plugins messing with each other but only when the form is in the "fillable" stage?
I'm not familiar with the Simple Select All Text Box, it's possible they are interacting in odd ways.
