Posting on behalf of a friend: RH6 to RH7 CSS conversion (using FM) gets messed up

[SB]

Posting on behalf of a friend (I must confess that I don't know much about
RH at all).

She has an existing Help 6 project, migrating out to RH7.

She wants to import Frame files for new help topics and replace others but
still keep the CCS from the Help 6 Project.

When she does it, the style sheet gets overwitten by a new one and it looks
awful. How can she fix this?

Thanks,

Sylvia
