#12 Highlighting tracked items

[Analia]

Hi all! I've just started using this javascript menu. I
had no troubles setting the menu and most of its
options, but there's one option that I unable to deal
with: the track color and background.

I would like the same appearance shown by the menu that
supports <http://www.treemenu.com/>. Once I select an
item I would like that its background and/or its text
color would change. However, even do I've tried to
manually configurate this recurring to the
MTMTrackColor variable and included the line
MTMExtraCSS.addRule('a.tracked','color:#000000;background-color:#e0e0e0;')

just before setting the icon list and the menu itself,
it didn't work!!!

Could anyone tell me what I'm doing wrong?

Thanks!
