Please describe the problem:
When I select Edit>Preferences and select the 'Accounting Period' tab, I cannot manually insert my own start and end year dates.

For instance, my start year date is 15/12/2007.  It automatically reverts to 01/08/2008.

The same applies to when I want to insert my own end year date.

I want to have flexible accounting periods.  They may not always by a full calendar year and they can start on any day, not the beginning of the month or year.

Help very much appreciated.
