Andreas, Ok I understand. I currently have a loader wheel running using loadstart/loadend but I would like to control the icon at the tree node. I have found that you can change the default image at the node level with iconCls: 'my image class'. However, I can't figure out how to change the className under program control.
For example, I can place a listener on the treePanel which allows me to interrogate the node selected ('checkchange':function(node)(...)) whenever a checkbox is clicked. However, inside this function when I look at the node's iconCls its 'undefined' and yet there is an iconCls set for each node in the tree - either the default one or one that I set. So without access to the iconCls for a node I can't see how I can use the loadstart/Loadend to control the node's image className? There must be something I'm missing here???

The JSON tree loader in GeoExt has this throbber, spinning until the JSON response is turned into layer nodes. It is, however, possible to achieve this on the application level by registering for the OpenLayers Map's loadstart and loadend events. Andreas.
