RoboHelp 8 utilizes DHTML, unlike previous versions. So if your project(s) are like mine, where you pick a style from the drop down (Heading 1, Heading 2, RRoundBullet, etc.), then you'll probably have all of the headaches that I have had in trying to make these styles work correctly in RH8. I've spent way more time that I should trying to stop bulleted lists from displaying numbers and so on.
You may want to consider RH7 if you use those styles and are not well-versed in DHTML coding to fix these issues.
Thank you for the information.
