Thanks for your reply. I figured it out. It appears to be a video resolution or window/workspace-sizing bug in v8 Emergency disk.
I had noticed that on my sytem all dialog boxes (and even the startup splash screen) would appear at the extreme right side of the screen, instead of being centered. See attachment image 1 below.
As it turns out, the main program window (at its default maximized size) is also extending way past the right edge of my screen, with the Folders pane taking up the entire visible screen width. The Contents pane is actually beyond the right screen edge (and therefore not visible). That's why I couldn't see any of the files. See attachment 2 below.
Luckily, I can get around this by de-maximizing the program window, dragging it to the left, and re-sizing the Folders and Contents panes as necessary. See attachment 3 below.
It seems like the program is not properly sizing the workspace in accordance with my monitor's resolution.
Hopefully R-TT will address this bug, but at least I now have have a workaround.
