Change cursor to hourglass

Is there any way to change the cursor to a hourglass after clicking on a tab? I can have a couple of second delay before the ajax call completes and I would like to change the pointer to a hourglass so the user knows something is happening.

Thanks,

Erik

Take a look at http://www.echoecho.com/csscursors.htm
Using javascript, to show the hourglass when the mouse is over element with ID ElementID, you would write something like:

document.getElementById('ElementID').style.cursor = "wait";

You can use the following to get back the default cursor:

document.getElementById('ElementID').style.cursor = "";
