page header

[Harald Zielstorff]

I'm writing my dissertation with lyx. 

I've got have a problem with the page headers. I'm using the 
dokument class "book". The titles of the sections are shown in the 
page headers. If the title is longer than one line, the title will be 
written over the right end of the page.

Is this a lyx- ot latex-bug?
