No idea but a distant bell is ringing to say I have heard of this once before. You haven't said what version of RoboHelp you are using but it was several versions back.
The post could well still be accessible but good luck finding it.
See www.grainge.org for RoboHelp and Authoring information
I have also seen this happen with some of our projects. We are fairly new to RoboHelp and have developed some bad habits that we are trying to break.
Sometimes the easiest (and quickest) way to get out of the loop is to use Task Manager (Windows) to kill the application.
Between RoboHelp and SharePoint we have a URL character limit of 255. This includes folder names, topic filenames, bookmarks, and drop-down (DHTML) text.
Our solution (still evolving):
- Go through the offending topic and shorten the aforementioned factors wherever possible.
- Right-click the topic and select Explore to view the files in the same folder as the topic. You will find a bunch of extra files that have a bunch of #s in the filenames.
- Delete the offending files (!! not the original .htm file !!)
- Using a text editor (like Notepad++) open the [filename].fpj file.
- You will see a bunch of <topic> tags. Delete the topics (including the topic tags) for all topics that have the #s in the name. - there should be many. (!! Do not delete the original .htm topic !!)
- Go back into RoboHelp and save the topic again.
- Generate/Publish as usual. If all of the long bookmarks, filenames, drop-downs, etc. are fixed, it should fly right through.
As always, your mileage may vary.
Hope this helps.
