You have this in the css:
Code:
.leftBoxContainer, .rightBoxContainer {
	background-image:url(../images/sidebox_content_bg.gif);
	background-repeat:repeat-y;
	margin-top: 1.5em
	}

.sideBoxContent {
	background-image:url(../images/sidebox_content_bg.gif);
	background-repeat:no-repeat;
	padding: 0.4em; background-position-y:50%
	}
I have ver 1.5 of the template and this in the css:
Code:
.leftBoxContainer, .rightBoxContainer {
	margin-top: 1.5em;
	}

.sideBoxContent {
	background-image:url(../images/sidebox_content_bg.gif);
	background-repeat:no-repeat;
	background-position:bottom;
	padding: 0.4em;
	}
For some reason yours is calling the image sidebox_content_bg.gif twice
