Using CQRLOG 0.8.5 on Ubuntu 9.10.
If I edit an existing QSO and leave the Frequency field blank, when I hit the "Save QSO" button I get a dialog that says:
"" is an invalid float.
Press OK to ignore and risk data corruption.
Press Cancel to kill the program.
I'd like an option to let me go back and fix the problem. Accepting bad data or killing the whole program seems rather harsh.
