This was working well with 2.8.
Browser version FF 13.0.1
Am using layerID.hide() & layerID.show() to toggle visibility on a GraphicsLayer.
Once I show(), the layer starts floating independently of the map.
Am using three graphicslayers.
Using setVisibility(true) helps to some extent (no pun intended). GraphicsLayer pan at the end of Map's Pan event.
Please help!
