Row 7 column 11 is not an input field on my display. When I hit
Shift-Tab, it goes to the "Position to" field, and does not lock up.
The reason it says that the file was removed is because James Rich
reorganized all of the source code in the project back in 2006.
The code in that source file does not seem to fit the patch you've
provided. Is it possible that you're looking at a very outdated copy of
the source? Do you have the same problem if you use the current copy?
