Hey, i'm Tobi :o
Sorry for my Bad English T_T...

I have something like my own Engine for Games and Programs, im using WinApi ofc. and my question is about Mouse Buttons

Left Right and Middle ( Wheel ) buttons every one know where they are X1 and X2 are on left side of Mouse but there is more button that Windows CallBack can handle...

I want to ask about those buttons:
WM_NCLBUTTON
