Hey, I just aksed my self how to use nested structs in the clean way. I can't set a namespace for the nested structs and so i'm not able to use them properly. Is there a way to fix this? Do i use wrong syntax on dllstructcreate? or is it an autoit-side bug?  Global Const $tagMINMAXINFO = "struct ptReserved;long X;long Y;endstruct;" & _ "struct ptMaxSize;long X;long Y;endstruct;" & _ "struct ptMaxPosition;long X;long Y;endstruct;" & _ "struct ptMinTrackSize;long X;long Y;end
