jQuery conflict?

I’m developing a site in Joomla 1.5 which uses the following slider

I added the swMenuFree module for Joomla to create a multi-tier dropdown navigation. Upon activating, however, the slider no longer shows up.


<script type="text/javascript" src="/templates/mmtcnew/js/jquery-1.4.2.min.js"></script>

    <script type="text/javascript" src="/templates/mmtcnew/js/jquery.wt-rotator.js"></script>
	<script type="text/javascript">
    	$(document).ready(	
			function() {
				$(".oneColElsCtrHdr").wtRotator({
					width:938,
					height:430,
					background_color:"#FFF",
					button_width:24,
					button_height:24,
					button_margin:4,
					auto_start:true,
					delay:9000,
					transition:"fade",
					transition_speed:800,
					block_size:100,
					vert_size:50,
					horz_size:50,
					cpanel_align:"BR",
					display_thumbs:true,
					display_dbuttons:true,
					display_playbutton:true,
					display_tooltip:true,
					display_numbers:true,
					cpanel_mouseover:false,
					text_mouseover:false
				});
			}
		);
    </script>

After some googling, I found that by switching each ‘$’ to ‘jQuery’ in the code above, I was able to get both to function properly, but only in Firefox. Using Chrome, Safari, and IE, I still get no slider. Has anyone experienced anything like this before or know of a solution?
