I'm attempting to get my points to plot based on the example Christopher
referenced (http://openlayers.org/dev/examples/sundials.html). Although
it appears to plot ok initially, if I pan up and down on the map, the
points will move up or down as well. Is this a problem in the javascript
or could the problem be in the kml file? I've included the code below
hoping someone might see the problem, and here's a link to the page:
http://www.erh.noaa.gov/ilm/viewer/plotLSR.html?lat=34.20&lon=-78.8&zoom=8&kmlfile=lsr080626.kml

Thanks,

Ok, please forgive my late night googling skills (tired eyes!), and thanks
for the prompt response. If i look at that link you have said:
"Generally, the answer is 'no, and why are you still using a Layer.Text?
Use a Layer.GML with a format: OpenLayers.Format.Text and a
selectFeature control instead.'
The reason why I am using Layer.text is because I specifically don't want my
end users to have to select a tool to click on a feature/marker.
They shouldn't need to.
var control = new OpenLayers.Control.SelectFeature(layer);
map.addControl(control);
control.activate();
Now the select control is active, and clicks on the features will
activate a popup.
See, for example: http://openlayers.org/dev/examples/sundials.html
