[OpenLayers-Users] force update markers layer

[Jan Hartmann]

I tried Layer.Markers.redraw(), but thet didn't solve the problem: the 
markers only moved to their new position,when their lonlats had been 
changed, after an addition zoomin or zoomout. In your map the markers 
always remain on the same spot.

Cheers,

Jan
