Bob,
You can at least drag the hacker.chm file into the right pane and add it to your favorites list. I'll ask up in the MVP newsgroups and see if anyone there knows more info about why some .chm files don't work in the col file.
>As you say... it must have soemthing to do with how the .CHM files are compiled, or there is another file that knows about them.. cause I can use existing .chm files, move them around, change titles, but I can't get external .chm files to work as part of the collection.

>To bad.... would be a nice feature of HTML Help to allow you to add .chm files to a colleciton... since you can already define subsets... hmm.
