You might open Fargo and find that it doesn't load as you expect. You don't see any of the icons that should be on the left side of the page, you don't see the T-Rex or any of the items on the right side of the page, if you have one, your menubar.opml items don't appear, and you don't see your name where the account settings drop-down menu is located.

Here is a link to a screenshot of what I described above.

Fixing the problem

1. Close the tab or browser window in which you opened Fargo

2. Log on to your Dropbox account

3. Click Apps, smallPicture, #prefs

4. Right-click tabs.json and select Delete

5. Open Fargo in a new tab or browser window

Fargo will load as expected, but you will not have any open tabs. At this point you can select File, Open to open any outline you have been working on and edit it as you expect.

Reproducing the problem

1. Have at least one tab with one of your outlines

2. Open an outline using either File, Open by name, or File, Open by URL

3. Exit Fargo by closing the tab or browser window in which it is loaded

4. Open Fargo in a new tab or browser window

So far, every time I follow the steps above using either Chrome or Internet Explorer, I see the loading problem as described above. The problem appears to be triggered by keeping an external outline open when exiting Fargo. If you close an external outline before exiting Fargo the problem does not occur.
