If you look at that screen capture you supplied it is clearly visible that the two window definitions are WebHelp window definitions. As far back as RoboHelp X5, we had the two Window types and what you got when creating a new window was dependent upon what your Primary Layout was configured to be.
Here is a screen capture from X5 for you to reference:
So even back in X5, in order to create a CHM window definition, you first have to nominate Microsoft HTML Help as the primary layout.
This is even more confusing in that when you were making the edits to the window definition it clearly states WebHelp and the dialog is totally different. Not sure how you missed that.
Have you ever considered attending a RoboHelp class?
Well, well... I never used Windows settings for WebHelp before - that's why I missed the heading; the only ones I ever saw or used were for HTML Help, and I rarely use that as Primary Layout. WebHelp is my customers' preferred build, and I only run HTML Help is a secondary layout for comparison of appearance. It seems, from what I can find in the Help Guide, that WebHelp windows only apply to WebHelp Pro - which none of my customers ever wanted.
So I've learned something - if WebHelp is primary, I have to select HTML as primary before I can create the Window; then switch primary back to WebHelp. But for ordinary WebHelp, these Window settings don't apply anyway. Thank you. (I did a RH X5 course and still have that 600-page Manual; I only wish I could afford a course every time the next version of RH is released.)
Yeah, there aren't all that many folks using WebHelp Pro.
Actually the dialog is a bit misleading. While it certainly reads WebHelp Pro and certainly applies to that format, it also applies to good old WebHelp and FlashHelp outputs too. That is, as long as you are using the WebHelp API to manage Context Sensitive Help.
Yes, I recall that being a trip up spot in X5 where things changed based on what the primary layout was configured to be. And that was one of them.
It would be nice if we were simply provided an intermediate dialog that prompted us to choose the window type we wanted, eh?
Hint hint - Everyone Click This Link and Suggest it!!!!
I sent it through the Wish List.
Interesting - the Wish List stopped me sending a message of more than 2000
characters; so I trimmed it down to 1800 (character count in MS Word) and it
STILL wouldnt accept it. So I had to split it into two and it went through
