--- Comment #1 from Daniel Santos daniel.santos@pobox.com 2010-06-13 15:30:56 --- As per the comment here: http://bugs.gentoo.org/show_bug.cgi?id=322697#c8 , this effects Dungeons & Dragons Online as well, which is a sister application to LoTRO, developed by the same company. The source of the problem has yet to be determined.
