Looks like I solved it...
PHP Code:
name "airstrike"
rect -83 0 1366 769
focuscolor AIRSTRIKE_FOCUSED_COLOR
style WINDOW_STYLE_EMPTY
onEsc
{
close airstrike;
}
1. -83 is the original position of the first column of elements - the first two columns had negative values;
2. I'm using 1366 instead of 640 - the position of the last two columns was higher than 640;
3. I transposed all elements in the menu by adding +83 to their position value (so the first column is now positioned in 0, and not -83).
Everything works, but...
editted: oh I think I get it now...
