Comment 3 for bug 1012734

Hello. In recent days I have noticed this strange behaviour.
When I start Writer or Impress (I haven't lock thier icons on the launcher), it can happen that:
a) it is not listed between the applications in the launcher (and even in the ALT-TAB window there is a "hole");
b) may be in the launcher but lower down, with a grey empty area between the last icon and the Writer icon.
