不能正确恢复notopmost；只能topmost

if SpeedButton1.down=true then

begin

SetWindowPos(Application.handle,hWnd_TopMost,
0,0,0,0,SWP_NOMOVE+SWP_NOSIZE);
SpeedButton1.Down:=false;
//end;

//if SpeedButton1.Down=false then

end else

begin

SetWindowPos(Application.handle,hWnd_NoTopMost,
0,0,0,0,SWP_NOMOVE+SWP_NOSIZE);
//SpeedButton1.Down:=true;
end;

//不能正确恢复notopmost；
