Group background does not work ok in IE

Hi,

I want to set background for "group" element and in IE it is displayed incorrectly, background is applied not only to internals of the group but also to the area above the legend, that looks really ugly.

I do it as this:

.aw-ui-group {
    width: 400px;
    height: 100px;
    border: 1px solid;
    border-color: #838383 #838383 #838383 #838383;
    [b]background-color: #EDEDED;[/b]
}

how would you suggest that the background look around the caption? Should it be half/half split down the center of the caption horizontally? You will find that with most programming languages, the group control background extends above the top of the control even if there is no caption. This is normal, it's not an IE bug.
