Greybox, the pop-up window: http://orangoo.com/labs/GreyBox/

I'd just like to know how I can get it to pop-up not in the center of the page.
I'd like it to pop-up on the left side of the page.
Is that possible? If so can you help me accomplish this? I looked at the CSS and I, and others, tried to modify without success. it may need some added code. Any help will be appreciated. Thanks.
