</div>Don't destroy the layer before creating a new one. Create a new layer,<br>
and destroy the old one when the new one is loaded (i.e. in a loadend<br>
event handler of the new layer).<br>
<br>
An even smarter way would be to not use a Markers layer, but a Vector<br>
layer with HTTP protocol, Text format and a Fixed strategy. Then you can<br>
just load the new text file, and there will be no flicker.<br>
