Hi Bill. This might be your most useful program yet! But there is a viewing problem on my screen (and probably on some other peoples' screens too).
The text in the box where one inputs data, is all jumbled up and smooshed together and hardly readable. The time zone check box doesn't appear. thanks for telling us about it. John John L.
