The expand chat button (plus sign) is a little lower, almost hidden beneath the collapsed window as it rests in its default, closed state.
I used Firebug to move it up a bit using negative margins but after clicking on it it is too low up top (in the expanded chat window).
When it was in that expanded state I deleted my changes in Firebug (to the margin) and it was placed nicely. Then, after collapsing the chat box the plus button was in the right place.
In other words, in order to get the chat box 'expand' button to display correctly I need to expand it once then collapse the message box.
Not sure what to do or what to edit to make it display right in both states.
