You can check it out yourself by editing a story in LC and clicking
Choose Topics, but there seems to be an extra phantom topic at
the top of the scroller list, one with no name and tid 0 apparently.
Its HTML is:
<span id="st-line-1" ondblclick="st_ok()"
I don't see this on slash.mccarthy.vg.
And I did a Dumper() of LC's topic tree and it looks fine.
So I don't know what's going on...
