"Loading" image

Hello, colleagues!

OrgChart 3.0 SP2 (Live connection).

When am expanding views -clicking on pluses, system works on request some time and then outputs result - new tree of Org Structure. As long as I have realy big structure, system implements my expanding few seconds, whil it does it I want to show user "Loading image" via gif crcle as it is in some cases in OrgChart.

I 've got an idea - when calls RFC_CHART from app, call new window in browser with gif image. Actually terrible idea.

Best regards,

Alexander.
