     Type:  bug           |      Status:  new         
 Priority:  minor         |   Milestone:  2.11 Release
Component:  Map           |     Version:  2.10

 In 2.5 this same bug was fixed by #813.[[BR]]
 But 2.9 reintroduced it due to #2111.

 You can see the effect on the [http://www.openlayers.org front page of
 OpenLayers].

 Steps to reproduce:[[BR]]
 Go to [http://www.openlayers.org www.openlayers.org].[[BR]]
 Open Firebug and go to Net-tab.[[BR]]
 Refresh page.[[BR]]
 *'''Notice that when the map loads the first time tiles load
 correctly.'''*[[BR]]
 Change the base layer to "Imagery".[[BR]]
 *'''Notice that two requests are "aborted" and will continue to display
 the loading indicator'''* - This is caused by the setVisibility(true) as
 outlined in #813.[[BR]]
 Changing between the base layers will give two "aborted" requests for each
 change.[[BR]]

 See attached image for example.

 I propose
 [http://trac.osgeo.org/openlayers/attachment/ticket/813/setBaseLayer.patch
 the patch] in #813 go back in.
