Wildfire 4.0 M050

Howdy,

I just installed Wildfire 4.0 M050 and have some odd things. On the left side, it does not allow me to navigate and set my working directory. Is there a setting that I need to re-activate to allow this? I can go into File-->Set Working Directory to do this but then the "Up one Level" button and others do not work. Have any of you out there experienced this, and if so, found a resolution?

Thank you,

James Westerfield
