I'm completely new to LaTeX - just started this morning, and I've come up agaisnt an annoying problem. For some reason when I compile my LaTeX code the vertical position of the Chapter 1 heading is higher than all my subsequent Chapter headings. Below is a copy of the master file I'm using as well as
\documentclass[12pt,a4paper]{report}

As you can see, the format of the called chapters is exactly the same, so why would Chapter 1 appear to be higher on the page (when compiled and viewed as a pdf) than Chapter 2?
Could it be something to do with the page numbering code that occurs before calling the chapter sections? Also, I don't know if it's relevant, but I'm using TexMaker to compile my code.
Many thanks, Chris
