SyCoDeR is right but I followed a slightly different path though probably with the same results.

/*Container, container body, iframe*/
.mce-tinymce, .mce-container-body, #code_ifr {
    min-height: 100% !important;
}
/*Container body*/
.mce-container-body {
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
}
/*Editing area*/
.mce-container-body .mce-edit-area {
    position: absolute;
    top: 69px;
    bottom: 37px;
    left: 0;
    right: 0;
}
/*Footer*/
.mce-tinymce .mce-statusbar {
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
}

Revised because TinyMCE changes the id's with menu/toolbar additions or deletions. This works no matter what you do with it.
