Unable to select second file after closing first file

[wilkinsw]

Using v0.8.0-gb60f4eb

This issue has to do with the column on the far left of the window that lists all open files. If you have two files open, and you close the one at the top of the list, the screen will clear and you can not re-select the file that is left.

Steps to reproduce:

1. Open a file
2. Open the same file (there should now be two files in the column)
3. Confirm that the top file in the list is highlighted (selected)
4. File -> Close File

You should now have the remaining file highlighted but the window never switched and you cannot reselect the file. I should note that everything behaves fine if you close a lower file in the list, it is only closing the top file that has this issue.
