'Page Background' Problems

[Angels1928]

Hello everyone,

I'm developing a skin for vBulletin. I'm in the process of coding it--but there's only one problem. This skin is a total b**** to code as I didn't take the layout into consideration (it's my first vB skin). Without going into details about the rest of the skin, here's my first problem:

I have my page background set to an image that repeats vertically (reason why I'm using page background, and not anything else--see above. B*** to code. My last resort). The problem is, near the footer, the background image suddenly shifts to the right about 5-7 pixels. This isn't good as it makes my website have a small scroll bar on the bottom, allowing me to scroll those few extra pixels.

Any ideas on how to fix this?

Here is the code I have for the background image (put into the main Page Background's Background text field):

#1d1d1d url(http://my-website.com/DIR1/DIR2/background.jpg) repeat-y;

I've attached a picture of this issue.

My second problem also pertains to the background image. On the main forum (where it shows all the categories, etc), the forum displays fine. However, when I view a thread, the background image starts again in the post. The image is a fixed-width, 1250px-ish design, so it makes the forum very wide. This might not make sense, so I've attached a picture of this as well.

Any help would be appreciated,
Angels
