If you stack, cascade or overlap, we STRONGLY recommend that you use Windows Vista® or Windows 7® with an Aero theme (usually the default theme). The "Glassy" Aero effects allow TableNinjaFT to read background tables.
If you decide to stack, cascade or overlap in Windows XP or in Windows Vista/7 with the "Windows Classic" or "Basic" theme unfortunately the default bets may occasionally fail to be set properly. Tiling your tables or playing with "NoOverlap" should work fine on any operating system.
