Backdating Data Entry for Date Fields

I have a user who does TONS of data entry for dates in the prior 2 months. Typically in January she would set her system clock back a year so that FileMaker autocompletes the correct year after she enters just the month and day in the date field.

This worked great with FM Server 5.5 and Client 6. However, since the 8.5 upgrade, she will lose her connection to the server and be unable to reconnect after she backdates her client marchine (this usually happens not during data entry, but when she tries to make a new record, so she loses 20 entries every time it happens. It was a huge pain to figure out the cause).

1. Is this a known issue?

2. It is unwise to ask this person to do the additional data entry for the year, because of the quantity of data entry. Also, the file must remain on the server. What is the best solution?

My first thought is to create a script to backdate all of the entries after the fact. Any other ideas?

Thanks,

Carmen
