I wanted to set the margin of a document. I changed the page setup Top, bottom, left and right to different value than the default.
I saved the document with the new margin, then closed the document.
Later on, when I open then print it, the margins are not correct, but followed the default margins.
I did some tests and realised that the page margins always in the default margins. SMath cannot save the page margins.
The behavior happens both in my windows and ubuntu machines.
