I am using a a customized google map which is used to show properties for sale in a specific area. There tree level for this ie by Country, State and City and is done using list menu. It is working properly, It is showing markers when any item is selected. markers are added using ajax. But my problem is,

If a country has many results it is taking long time to show the markers. I need to display some message like "loading..." or something like that to make it a bit user friendly. Also this delay is found only in Internet Explorer 6.

Please help me
Thanks in advance :)
