Not sure if any of you have come across this bug in Quizmaker or not? Basically if you bold part of a sentence in Quizmaker, the bold text will be shifted down 1px. This is shown in the image below:
So I've figured out a quick easy fix to this problem.
Instead of bolding the text, simply change the font to 'Arial Rounded MT Bold'. As you cna see in the image below the result is near perfect.
