I am designing a scenario that takes place in the Elizabethan era. I want the time increment to be months. According to the documentation, I should be able to enter a negative integer in the turn year increment box. But when I try, nohting happens. I am not allowed to enter any character other than a positive integer - pressing the minus key [or any key other than a number] has no effect at all. Has anyone else experienced this problem? Is there any way around it?
