Grapich Control over Pic Control possible?

[malu05]

This is in relation to my ASCII portal editor.

Here you see the UI of my App

The dark grey area are small tiles of 10 by 12 Pic controls.

Now what i wanted to do is make a option to add a grid to easily see the tile area.

The grind should be made with the grapich control (just a line)

I see in the documentation for GUICtrlCreateGraphic that "If overlap is needed it is important to disable the graphic control : GuiCtrlSetState(-1,$GUI_DISABLE)."

But even if i do that it does not overlap my "pic" controls.

So is there a way to make "GUICtrlCreateGraphic" overlap "GUICtrlCreatePic"?
