Yes. On Windows Starry Night looks to the Windows registry to determine the order in which to show dates. If it can't find a registry entry for regional date settings then it defaults to the US month, day, year. Unfortunately UK Windows does not automatically place the date format in the registry where Starry Night expects to see it. To work around this you should open the "Regional Settings" control panel, switch the date format to something other than the current setting, click OK, then reopen the "Regional Settings" control panel and switch to the UK day-month-year order. After restarting Starry Night it should be using the new date format. On the Macintosh you can reset the date format from the Date and Time control panel. After restarting Starry Night it should be using the new date format.
