I'm trying to create my very first theme and I'm having trouble setting the image for the taskbar.
After setting the image and the margins this is what I get

This is the image I used:

I set the margins to 5,5,128,133,185. I set the width to the screen width via scripting.
Now, when I apply the same image and margins to Q's Counter Element theme I downloaded it works fine.

What am I doing wrong? Any suggestions at all?
