[lmi] solve-related durations

[Wendy Boutin]

I think there's an issue with the new solve-related
age and time inputs.

'ToAge' type in a different age and the default
age is automatically re-displayed instead of the
entered age. I can re-enter the age and it will
stick after another try, or two.

This is just one example--I observe the same behavior
in the other age and year input fields that are similarly
connected, i.e., *not* 'IssueAge'.
