Double Clicking Bin not opening in new window

Thanks Rob for your help.

But it did not work.

I discovered that what was happening was that after I doble click on the Folder, it would next open up the detailed list inside of that folder in the same place, instead of opening up a new window as should usually be the case. 

Then I tried to 'undock' that window. And it worked. The detailed list of the contents of the folder then became the new Window.

This is not an ideal solution.But somehow it works with an additional step. 

I was wondering if there could be an option in the 'Preference' menu something like this

Double Click on Folder - (Select Option)     1 Opens up New Window

                                                                        2 Opnes up in the same Window

May be some keyboard shortcuts outside the Premiere Pro or in Windows Default (if there is any) are overriding on the Premiere Pro shortcuts and neutralising them. Perhaps there is a way to make PP shortcuts override the System shortcuts or the shortcuts of other programms.

Though somehow I managed to achieve my goal, my original question is still begging for a solution.
