Pagenumbers gone in pdf with lyx 1.3.2

[Robert Neumann]

Hello,
I am normally using Lyx 1.20, but I'm planing to switch to lyx 1.3.2. When I 
open a document which was created with lyx 1.20 using fanyhdr I encounter a 
problem: When I use the pdf preview or export function, the pagenumbers 
(created with fancyfoot) were gone. If I'm using the dvi preview, everything 
is ok. Can anybody help me with this problem?
Thanks
Robert
