Advanced Menu Caja, Cairo dock problems

Hi. I have two problems and thought that I would post here. The first problem is that after clicking on the Advanced Menu button, if I try to click on Computer or Trash, instead of those locations opening in a Caja window, a Transmission window opens. I was wondering what to do to fix the problem so that the Caja window of those locations open.
The second problem involves the dock software of Cairo; if I go to a terminal and type "cairo-dock -ma" then select "Themes" in the newly created window that appears, after selecting any theme, the Cairo dock window locks up so that I have to go into System Resources to kill the Cairo app.
I was wondering what to do about these problems.
