- Does not move loading object to correct position in Firefox. (1.5+)
- Scrolling with the mouse does not correctly postion in Netscape (8.+)
- When right horizontal:
	- infinite scrolling occurs in Netscape (8.+)
	- padding / margin should be set properly for Firefox (1.+)
- When using IE6-, dropdownlists display above background object.

// Allow the user to vertically align the object: top (0), middle (1), bottom (2)
// Allow the user to horizontally align the object: left (0), center (1), right (2)
