Radar synchronize

Hi all,
Can anyone help me to synchronize the radar position correctly? I did all the way like setting the heading, but it waste my time while doing hit and trail on heading position.
Here is what I did . My tour hlookat position is always -17.
And one more thing I am facing problem in cache of krpano.swf

var swf = createswf("/krpano/krpano.swf");
alert(new Date().getTime());
swf.addVariable("xml", "/krpano/1114.xml" + "?nocache=" + new Date().getTime());
swf.embed("krpanoDIV");
above code works for first xml e.g. for 1114.xml but how to implement this with loadpano(/1120.xml, null, MERGE, BLEND(1))?
Thanks in Advance</plugin>

Thanks Klaus
For the radar orientation I found this post "radar orientation" which helps me to solve my radar synchronization problem.

And caching problem, I solved with the help of external javascript. Here I'm sharing what I did.

<script type="text/javascript">
function Caching(xmlFile) {
var xmlPath = xmlFile + "?nocache=" + new Date().getTime();
var swf = createswf("krpano.swf");swf.addVariable("xml",xmlPath);swf.embed("krpanoDIV");}</script>
<plugin name="myPlugin" url="mappoint.png" keep="true" parent="map" align="lefttop" edge="center" x="307" y="180" zorder="2" onclick="js(Caching(krpano.xml));" />

Thanks once again for such a nice featured 360 viewer.
