Hello,
Thank you for your answer.
As you can see, in the page 2, on the footer frame, text overlaps as if tab was not correctly handled and the page number is completly on the right, glued to the end of the frame.
Page 3 and 4 display correctly (and are slightly different : page numbering is not the same). And there is a gap between the page number and the end of the frame which I understant beeging the rendering expected with the "right" tabulation.
I expected page 2 be with the same rendering as page 3 and 4 (modulo page number of course).
B.R.
