Hello,
   Trying to make a 3 fold pamphlet, but not able to evenly split a page into  
3.

Ok, here is what I have done: Select Single page in document setup, A4 paper,  
landscape, make all margins 4mm. No bleeds. unit of measurement Millimetres.  
Apply all settings to all document pages and master pages.

Next once document is open, I go to Guide Manager and in the column/row tab I  
select 2 vertical, using 8mm gap referring to Page.

All done, this does not produce and even 3 way split across the page. You can  
see this yourself using the ruler feature in Scribus - the central column is  
always 4mm wider than the outside two.

Where have I gone wrong or how can I make the split exactly 3 even columns?
