On your missing minimap, check the Z-order as I mentioned at I-Mod. Just seems to get thrown off for no apparent reason and can drive you nuts wondering how something got stuck under the background

. If that doesn't do it I'll try to think of something. Unless it's a top secret type thing you could send me that pack and I could play around with it an try to see if I can find out what the deal is.
The stretching is due to the scaling. Your objects should be setup as child to the mainbackground's parent. You'll have to use the commands like these;
Example:
Sub System_OnScreenChange
Object.Width = Object.Parent.Object.Width - 200
End Sub
there's also System.ScreenWidth commands that I believe have something to do with it, but I haven't quite delved into this aspect of it yet and have a very rudimentary understanding of these commands so far. Without the proper scaling though the display will look different to people using different resolutions. I recently was modding the GalaxyWnd and had sent it to a friend to look at and due to the lack of scaling some options were totally off the edge of his screen where they had been fine in mine. Not sure if any of this rambling will help, but if nothing else you know how little that I know
