Search for Microsoft HTML Help Workshop. It's downloadable for free on the Microsoft page.
It can decompile the 3dgs manual to a set of HTML pages.

Do this once and then you cna proceed as before. Why compile it again? You can keep the HTML version.

Of course it's some work to start up the tool and click the decompile button, but hey - if I read your post it should be worth to spend those 5 minutes.
