Okay, I pushed that change to ePub3-itizer master. I will wait a week or two to see if any other bugs are reported and then push it out as version 0.3.8.
Version 0.3.6 will continue to work well for Linux and Windows users. Mac users should choose Version 0.3.7, and then all users can update to 0.3.8 when it is released.
For all current and previous releases - see the ePub3-itizer github site:
