yes, the problem is that after you change the fontsize option in the
dialog, now there is no way to disable it, you have to close it and
open it again. Related ticket 1048 [1].

As for the cartographic composer, labels are not yet supported. I will
try to add it soon. Meanwhile, you can export the instructions file,
add labels instruction there and run ps.map with this file. Do not
forget to change region appropriately (region settings from the
instruction file header).
