Whoops, ignore my previous email. It looks like clf is actually clearing out the mouse pick callbacks. So after your clf call you will have to reset the mouse pick callback and that should do the trick for you. I guess you'll just have to add the picker callback in your update_data method. cheers, Prabhu ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
