I've had similar problems with CHM output. To display merged projects I've had to avoid using underscores in the output filenames and also re-merge the slave projects in the master. Otherwise, although the help file displayed fine on my PC a considerable amount of material was missing when the project was displayed on other machines. Re: Index in a merged project displaying differently on other PCs
Are you creating web help output?
I am creating WebHelp and the project name and output name is one word with no spaces or underscores. I have checked every flag/option in both the Parent and child projects and have not seen anything that would cause this issue.
One thing to watch for is the existence of multiple web servers. Often you will find in organizations that multiple web servers are used for load balancing purposes. During one page load, the content may arrive from Server A. The next request may find Server A too busy so it's then served from Server C.
One possibility here is that multiple web servers are involved, but are somehow configured differently. Perhaps where the users aren't able to see things unless they use an explicit URL, they don't have correct permissions.
Finger pointing games do nobody any real good. But your job here is to test the output on your local PC first. Does the merge work properly there? If so, show this to your web admins. Then contrast that with the fact it doesn't seem to work correctly 100% of the time in their enviornment.
Cheers and good luck! Rick

I was able to get the networking people to dig into this a little more. They are able to replicate both profiles for users who can see the merged project and those who cannot.
They have verified that all permissions are the same.
When they turned on logging, the user that could see the file logged access to the following files:
The user profile that could not see the merged project did not log access to either of these files. We now have this occurring on one additional project so we would really like to figure out the issue rather than rename every project that disappears.
