Background in Scrollbox - IE7 changed CSS effects Options

[Jen001]

Before, I had a code which worked for both Firefox & Internet Explorer, which was a hard thing to do in its own - Since one needed a code another cannot handle, I found out that the command "!important" was a nice solution

you'll see what I mean by this code:

It worked perfectly for both browsers, until IE7 hit. Then the background wouldn't even appear anymore. I suspect(through trial & error) its an issue with the "background-attachment: fixed" coding. Is there anyway to resolve this?
Any help would be really appreaciated
