Captivate 8 Quiz - Answer Text Boxes Are Not Consistent

The problem I seem to encounter continually with quizzes are with the size and positioning of the answer text boxes.  Here's an example of what I am talking about:

The red circle shows how my answer box spills over onto my background when I hover over the answer. 

Comparably, here is another answer on the same slide:

And here are my settings for both:

Both lines have the exact same X coordinates and, they both have the exact Width and Height dimensions.  Yet, when the quiz is tested, there is spill over of the text box onto my background. 

My client is very picky and this is really bothering him.  They need to be exactly the same width when rolled over. 

Is there a solution to this, or is this another bug?
