HTML Export does not seem to work in the Master Document Tool.  If you have a
master document with a few sub documents (I tried with a large document -- 200
pages and 10 sub documents, and with a test document of 2 small test sub
documents).  You get this by:

*  Create a master documents with 2 or more sub documents -- I tried empty ones
and ones with some text in them.
*  From the master select the menu:  File>Send>Create HTML Document
*  The application will hang or crash depending on type and size of document.

For the 200 page document I also got the message "Too Many Windows" which didn't
make much sense. 

Anyway -- HTML Export does not seem to work in master document.

This is based on my experience with OOo2.0.1 and OOo2.0.2RC1.  I use Windows
2000 5.00.2195 SP4.

I rated this a 3 because this is a useful feature that just does not work and
should, but I'm not certain how many people use this feature -- i.e. HTML export
in Master Document.

Take care,
