Well I see that the process was a little more complex and required some decisions. I believe what I did so far was to just replace the Linux operating system, which did not fix the problem. I see the other options are J-Field, Fonts and Geo-Data so I thought I might wait and see if a new Geo-Data file would be in the offing and potentially fix the problem. The pre-release and release versions of the Geo-Data are the same. But I probably won't be able to wait that long as I will need to use the unit tomorrow in the field. So at that point I will probably restore J-Field and then see if I have the ability to retrieve the older version of the Geo-Data. I just don't know what kind of settings rebuilding I will have to do after any of these possibilities.
