The applets are broken for the "Classic" layout if used on panel2 they loose the right-click menu.
Thanks Leigh, I was planning to test this.. didn't yet. Which applet in particular is broken for you?
Applets tested and found broken so far are
I suspect all applets added to panel2 will suffer the same issue with the right-click.
also window-list tooltips appear on the top panel (panel1) instead of panel2.
I have also noticed that the power applet is broken (I have two instead of one and one is broken).
