I have implemented a tooltip on my navigational links (after clicking on the 2006 Volvo 780). Found here: http://www.lonemountaintruck.com/partners/index2.php
I am pulling the "detailed" view of the truck into the div from a php file(loadtrucks.php).
The "Next Rig" link is the link that is causing the tooltip to stay open after you click it even if you click on "Pick A Different Rig" link at the top right, and it stays open until you actually reload the page. The link looks like this:
I found that if I use onClick instead of onmousedown, the behavior goes away. However, then I lose the jquery slide/show effect.
