Set the Windows system font size to 124% or less.
it is already.
i think it's rather indesign problem than window system because my illustrator and photoshop work fine.
It IS an ID problem -- ID looks at the system font size and if it's set to 125% or more it enlarges the interface because it makes the mistaken assumption that you have an ultra-high resolution monitor. The magic number is 124%
thank you so much.
