Camera Bounds Changing

How do I rid myself of the ugly lines on the minimap and lack of units on the minimap?

I think you have to import some .blps for the minimap lines - I'm not sure as to the exact path though so if you already knew this then ah well.

And what do you mean by lack of units?

There is a rectangular area on the minimap in which I can see stuff.

The Unit is hidden in this minimap image (I sent him to the red box):


In this one the unit is in the red box and visible:


The Problem is when I change the camera bounds I get grey lines on my minimap which block units from being seen. Can anyone give me a step by step on how to fix it?
