Custom paper size

[Yann Collete]

Hello,

I've got a little problem when tuning the paper size.
I've to write a paper using a 23cm - 14.8cm paper size.
So, I select custom, give the size in the paper dialog and
select "use geometry".
When I export to ghostview, the paper seems to have the right size
but some line at the top and at the bottom have disappeared.
I haven't set any margin, I really don't know where it comes from.
I use lyx-1.1.5fix2
