I apologize for the delayed resposne, although I have learned a few things reading this thread 
I am using RH8 and WebHelp Pro. I have not published my project using RoboHelp Server and I do not know how to access the Windows Properties screen identified by John. So...
- How do I get to the Windows Properties page
- Should I be using the RoboHelp Server (as we are going to break this project into Master and Child[ren] projects
As an aside, I no longer have the option of choosing WebHelp as a Single Source Layout. Can I retrieve that as an option?
Thanks for all of the knowledge shared by all contributors in this thread. I appreaciate it!
Cindy
Hi Cindy.
In addition to Rick's important distinction as to whether you are using RoboHelp Server or not, that is definitely the first thing that needs to be determined. The "Pro" Single Source Layouts are specifically designed to assist in publishing to a web server that has the *optional* RoboHelp Server application installed. There are many benefits to having this server (user feedback reporting and the ability to apply security levels and restrict access to various parts of your published website is among them.)
That said, if you don't have the RoboHelp Server piece, you will want "plain" WebHelp.
As to your question, "As an aside, I no longer have the option of choosing WebHelp as a Single Source Layout. Can I retrieve that as an option?"
1. Make sure the Single Source Layout pod is in view.
2. Click the icon whose tooltip says "Create layout"
3. In the New layout dialog, type in a descriptive name for the layout
4. From the dropdown arrow, select WebHelp (not Pro) as the output type
5. After you do this, the new layout will appear in the SSL pod.
6. Finally, right click this new layout and from the context menu, click "Set as primary layout" This is important as you proceed with Rick's procedure for accessing the correct Window Properties in the Project Set-up pod.
That should do it. 
Thanks
