That is not possible to do, i guess (or not,may be using Dlls =/, i dont know), just because when you set x y w h to the first tab, the other tabs assume exactly the same sizes as the first!
like :
Tab "Tab 1", 1, x y w h
Tab "Tab 2", 2
and you wanna create Tab 3, you dont need to set sizes for her, her just gain the same size as the first Tab (Tab 1)!
Thats all
