I have a TreeView control in an update panel. When the user clicks the plus symbol, the tree doesn't expand. I have also found that if the user clicks on the node, the node disappears until the update panel is updated by another event not associated with the tree control. Is this a known issue? If not, do you have some ideas where I should look for the cause? Everything works correctly in IE, just not in Safari, so I am thinking the browser is not able to parse the html being returned from the Ajax call.

Thanks in advance!
