Click on the Navigation Bar with the right Mouse Button and uncheck "Navigation".
You can do the same in the registry. Just goto HKEY_CURRENT_USER\Software\QlikTech\QlikOcx\Toolbar 7\State-Bar0 and insert a new "DWORD (32-bit) Value" called Visible. Value = 0.
I had this problem as well. I wanted navigation gone because of triggers occurring making it downright impossible to control forward and back through navigation.
No luck because I would have to remove them in all dashboards (not just the one I used triggers on).
