no problem

by the way, these two strings in the file pages-overlay.xul are not yet 
converted to entities:
  <caption label="Included pages" />
and
  <caption label="Excluded pages" />

they should be replaced with:
  <caption label="&manage.label.grpIncluded;" />
and
  <caption label="&manage.label.grpExcluded;" />
