When I add a feature with the exact same coordinates to both an InMemoryFeatureLayer and InMemoryMarkerOverlay, they are rendered at slightly different positions on the map. The feature in the InMemoryFeatureLayer seems to be rendered about 15px offset from the InMemoryMarkerOverlay.
This is extremely frustrating as I am using both type of layers and I need the feature positions to align up.
I am also using an OpenLayers Vector layer and it renders in the same way as InMemoryFeatureLayer.
I look forward to your reply.
