If the topics contains and '&'-char, the rest of the line gets trashed. I use FR to monitor new anime-releases and somtimes the groupname contains an '&'-char.
if "[A&F_MnS]Saint.Seiya.Tenkai-hen.Joso.Overture[VostFr].torrent" is the topic, all i see is "[A", which is frustrating. I don't know if the cut is because the char '&' or the html-encoded char '&'.
I've seen this phenomenon in all pervious versions i've tried, including the latest, 2.7 build 646.
