[OpenLayers-Users] Pan & markers issue

[Shaw, Richard A]

I have a marker on a layer which the user can move. When the provide the new location I use moveTo to move the marker to the new location.

This works fine most of the time but on occasion it put the marke in the wrong place. Finally I discovered that it fails if the last thing I did to the map was pan. The marker is position out of place by the distance of the pan. If I zoom the map before moving the marker it puts it in the correct place.

Does anybody know if this has been fixed - or how to fix it (I've tried searching the openlayers trac but I can't find anything). 

I'm using revision 4899.

Thanks

My line of code is -

originMarker.moveTo(backLayer.getViewPortPxFromLonLat(new OpenLayers.LonLat(newWgs84.longitude, newWgs84.latitude)));

Just about to send this and thought of something else. I get the position to move the marker to from the user clicking on the map with the following code. I thought it could be that the I need to adjust the e.xy by the offset of the layercontainerdiv before I convert the point to lat/lon but I added a display of the lat/lon and I get the same value before and after a pan, so it looks like the issue described above, but I'm having trouble trying to find where to put a fix.
