In the blue buttons for Post, Preview, and Cancel for a forum post, when you click in the region next to the right of the text, nothing happens. But when you click in the text or to the left off it, the button is pressed.

The bug probably results from this arrangement:

<div class="formButtonContainer"> 
   <div class="formButtonContainer">
       <button class="formButton " ... type="submit">Post</button>
   </div>
   <div class="formButtonEnding"></div>
</div>

For some reason, there are two containers. (Not sure why.)

It seems that the button's start-region is generated in the formButton class, but the end-region can't be generated there, for some reason.

It's not clear to me where the event goes. If it goes to the container, then it may be possible to solve the problem by putting both segments inside a single container, eliminating the extra one.

If the event goes to the "formButton", the problem may not be easily solved since, presumably, the difficulty of tacking on the end region was what caused it to become a separate item in the first place.
