Tested in Firefox 2.0.0.20

 

When I click the "Upload file" button inside any of the file upload dialogs, nothing happens and the following error is being returned through firebug: 

 

 

XML descendants internal method called on incompatible Window 

 

I am unable to reproduce this error on the demo's that have been set up but I have also re-downloaded and uploaded the full set of files without success.  I'm unsure of what to try next.  Any ideas or anyone else running into this issue?

 

Also, folder creation and editing works exactly as expected.  It is only when clicking the "Upload file" button that the error manifests itself.
