Nein, mit der A6 funktioniert das, ich benutz den Befehl immer so

Du hast den Visible Flag vergessen

Code:

///////////////////////////
VAR video_mode = 8;
VAR video_depth = 16;

Bmap metal = "menu.bmp";//use this picture
///////////////////////////
PANEL menu_pan
{
Bmap = metal;//use predifined picture
pos.x = 0;
pos.y = 0;
flags=visible;


}
///////////////////////////
FUNCTION main()
{
menu_pan.VISIBLE = on;//visible is turned on
load_level("menu_DG.wmp");//load in this level
}
