Fixed Background Image with Javacript

To fix a background image in the browser everybody uses background-attachment: fixed. However in IE this CSS property only works for the body tag while it works also for divs in Firefox and other browsers. So there must be a Javascript solution for IE. Please look at [this page][1] in IE. The body tag holds the yellow lines so the grass was placed into a div as background. I used a script that I downloaded [here][2] but as you see the background image jumps when you scroll up and down. Using IE expressions in the stylesheet results in the same behaviour. I found another solution: Dean Edwards' [IE7 javascript library][3]. Using this script the background image doesn't jump but it sometimes completely disapperars when the browser is resized. On the other hand the layout is messed up a little as soon as I link the library to the head section. Of course I could fix the CSS file but I don't want to fix a stylesheet that has worked before I added some Javascript classes. So what I need to be done by a Javascript expert: Take either the first one of these open source scripts ([login to view URL]) and fix it or write a new function. In the first case your fixes will be released to the open source like the original script. The script must work for IE 5.0, IE 5.5, IE 6.0 (Windows) and IE 5.2 (Mac). Once I selected a coder I will create FTP access for him to the [page][1] that I mentioned above. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
