no section numbering within lyx

[Till von Reumont]

hello.
i am using the os x aqua version of lyx 1.3.2. everything works 
perfectly except that there are no numbers in the sections and 
subsections of the documents no matter if the document is an "article", 
a "report" etc. the actual output is ok though, my ps or dvi files are 
all correctly displayed and printed complete with numbered sections and 
subsections. when working with large documents in lyx it gets a little 
confusing sometimes because the numbers don't show up. any idea what i 
could do?
thanks, [EMAIL PROTECTED]
