DOC file imported to RoboHelp 9 is not divided into topics

Hi All,

I want to generate CHM help file from the DOC file. So, what I have already done:

1. Remove all useless images and text in DOC (document covers, headings and footers, etc.)
2. Verify that headings are applied correctly to the DOC topics (H1, H2, H3...).
3. Create new project in RoboHelp 9 and import this DOC file.

Results:

Entire DOC file is imported to a single RoboHelp topic.... It was not divided into separate topics, regarding headings set in DOC.

The only thing I can do now is to create topics manually, and copy-paste the text into these topics..

As far as I remember some previous RoboHelp version allowed to set option like this: create separate topics in accordance with heading applied in Word or import the DOC into single topic..

Please, help me

Thanks,

Olga
