I'm using the JQuery tooltip plugin - http://docs.jquery.com/Plugins/Tooltip
With the basic implementation:
$(".tooltip").tooltip();
Instead of the tooltip placing itself over the input box it belongs to and tracking with the mouse it is placing itself at the bottom of the page.
The input is basic and is like this:
<input type="text" name="testTooltip" class="tooltip" title="This is the tooltip" />
I've stripped out the CSS in its entirity and the problem remains (there's no inline CSS).
Any ideas as to what could be causing this?
