I'm using the version from the Arch repositories. It works now--kinda. The problem was that nothing is selected under the 'View' button in the menu. When I choose 'File Browser' (and whatever else I'd like to see) it shows. Strangely, I've tried opening and closing things a few times and sometimes it goes blank again and I have to re-select 'File Browser.' Any thoughts on this?
And thanks for all of your help and responses
