TOC Widget description Event

I am using the TOC Widget and have it configured to usenewesridescription=false.

This way I get the nice little popup window with the service description information.

I have included a link to a web page in the description, and can click from the popup to follow the link.

I would like it to close the description popup when I click on the link, but not able to figure out where that popup is being handled so that I could try to put an onClick listener or something so that I can have it close the popup on click of the link.

Does this sound like a simple modification? If so, any idea where I would go to capture/handle this?

Thanks,
