   Message:
hi there,
I have this problem with Scribus,

"Create a two-fold document, and attempt to  export it to PDF. but  it is  
outputted as seperate pages, when they should be merged into one."
Ex :I want to have page 1 (single page), then page 2 & page 3 (two fold page  
-suppose to come together), then page 4 & page 5.....but when I export to  
pdf, it appear like page 1, then page 2, then 3 three, then page 4......

Pls show me the way what should I do
I use version 1.3.8

Many thanks,
Lyn
