This is good. It solves almost all of the lack of 'working' indicators in 9.2, that existed prior in 9.1 and in ArcIMS.

I'm doing some testing on this "busy indicator" stuff now. However, the error message always shows up complaining about a javascript error: "map.pendingTiles is null or not an object". Already installed the ArcGis Server 9.2 for .net service pack 2. Tried to set the "UseDefaultWebResources" to ture, or false(set the "WebResourceLoation" to "/aspnet_client/ESRI/WebADF/") but it doesn't help. I could find the "pendingTiles" properties inside the javascript file "display_map.js". However, it seems the old version of javascript is still loading instead of the new one which comes with the SP2. Any help will be appreciated.

This error is usually associated with an incorrect Map id. The sample above assumes the id is "Map1" when it gets the JavaScript Map object from the Maps array: map = Maps["Map1"]; Let me know if the problem persists.

Rex, My bad! I put the javascript code inside the form tag by mistake. Appreciate your help.:)
