Peter,

I agree with you and Brian that two progress bars is not useful. But 
FamilyLines is not the only report that has two progress bars, there are 
several, for example BirthdayReport among the text reports. I don't mind 
to see the "Processing File" progress bar disappear.

As for an explanation, I have non other than that threads make things 
much more complicated. I know, pretty lame.
