Linking CHM files

I need help with Robohelp. The question is related to hyperlinking documents. I use Robohelp to convert lot of word 2007 documents.

First let me explain about my system configuration. I work on Windows Vista platform, with MS word 2007 and Robohelp 7.0 versions.

1. I need a converted .chm file to locate to a particular section in a Word document. Can this be done? Word to Word linking is working fine, However when I convert it to .chm file it points out to the starting of the document and not to the particular section. Or I receive an mk:@MSITStore:C:\.... error and the file does not open

2. Can we create link between .chm to .chm file. For example, can we create a hyperlink from a .chm file to point to a particular header/part of another .chm file?

Kindly answer my questions as I should know the possibilities as I have a huge amount of documents to be converted.

Your help is greatly appreciated.
