"Add child page" doesn't work properly

Hello,

I'm trying to implement BookMadeSimple in a localhost site. I have 3 types of content, A B and C. An "A" content is the top-level page of book and may be combined with one/several "B" content and/or one/several "C" content. I configured BMS very easily. Once the different contents are created, I can file them as I want (an A parent + one B child). That's perfect.

The problem occurs when I create an A content, and try to create a child page. If I click on the Drupal's link "Add a child page", it works but I create a Book page (not a B or C content). I am able to change the type content name in the URL, so I can create a B or C child - but that's not very simple. Not possible for an active site.

If I use the BookMadeSimple's drop-down list, either "add a child page" or a B or C content, I reach a "file not found" error message. The URL looks like this : http://localhost/mysite/node/add/type_B?parent=653 ; I didn't enable clean URLs and the content type name spells with a dash (not an underscore). But if I manually correct the URL (adding the ?q= and replacing the underscore), I just reach the Create content page (http://localhost/mysite/?q=node/add) ; of course, when I click on "B content", I have to manually set the Book outline settings (I mean, the B page is not automatically included in the new book).

What can I do ?
Thanks a lot,
