[amsat-bb] SatPC32 observer changes unexpectedly

[Butch]

Fresh install of ver. 12.8d on Win 10
Running for first time and doing the following:
Enter lon & lat  (in my case -84.3, 36.0)
Register > enter data and password > get password is OK!
Tap OK, program runs, Obs. (in lower left corner) reads -84.3/36.0
All looks good, do nothing else but quit.

Run program again, get Obs. 8.9/51.9 … why?

Did this several times with same results.  
What am I doing wrong?
