I've been quite happy with the Windows version of Due Today (barring the duplicate issue mentioned previously), but there is one minor UI issue I find a little jarring. Every time I open the date picker to modify a due date it shows each row starting on Monday and ending on Sunday. I'm in Australia and our calendars typically have rows starting on Sunday and finishing on a Saturday when depicting a month. I believe this preference should be embedded in the Windows locale settings somewhere. Is there any chance you could please change the date picker to query Windows' locale information and display the week start date correctly for the user's machine?
