Maker 12 on Mac -- DITA to PDF, Links Broken

[Chris Despopoulos]

An odd problem...  I have a DITA publication, and I save as a Composite Document.  All is fine, except I have some hypertext links  implemented as markers on codeph text.  (That translates to text with a specific text format, ao it shold work like any hypertext marker.)  When I look at them in Maker, they're all correct, and the modifier keys show that they are treated as hover regions, and they display what the link points to.  When I save as PDF, I have problems.

Here's the funny thing.  Some of them work, and some do not.  I can take one that doesn't work, and copy it into the same part of the document where one of them DOES work, and that copy will work.  I can copy one that does work and paste it into the region where one of then does NOT work, and that copy will not work.
What I get in the PDF is straight text, formatted correctly, but no link action.  I can see nothing to indicate why one region of the doc can generate a working link, and another region of the doc cannot.  The structure is valid, everything looks right.  And in case you think it's position...  Links work at the top, and at the bottom, and at other arbitrary positions in the tree. I have a nested topic where the first such link does not work, and the second one does.  In other cases, the first link does work and the second one does not. In other cases non of them work, and still in other cases all the links in a topic work.

Now let's get even weirder...  I'm doing this on a Mac, running Maker within a Windows WM.  I can copy the file over to my Win machine, same version of Maker, and generate the PDF.  In that case, all the links work. 

Does anybody have a clue what might be happening?  And no, it isn't HTTPS vs HTTP.

Thanks for ANY input         cud
