You have icons in the menu with Position=>HorAlign=>ERA_HIGH_END?! Then, if you set their coordinates to minus 100, for example, they will always be minus 100 from the edge.
To be honest, I don't remember what I did and how xD
I worked on the menu for about ten days, figuring it out as I went along, and I still remembered what I was doing... the result is what it is, and now, after N months, I don't remember how I did it =)
