I know this is old, but I am having the exact same problem.
Except, I'm using a C# application. I can't get it to open up to my map id, and when I try selecting the search or index pages, it just takes me to the start page. Help or guidance on this will be greatly appreciate!
For anyone else who may have the same issue:
I didn't notice the little IE warning about blocked content from ActiveX. Enabling this content allowed me to launch help with TOC or Index, whatever OptionalContraint I chose.
