I have a tooltip working in my page. The following is my sample code.
Once I mouseover the "Help" label. It shows me the tooltip. Then when I move out the current page. Occasionally it gives me the following Javascript error.
Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.AddHandler method.
Any idea?

Hi Chris,
Unfortunately, I could not reproduce the problem by merely using your code. Could you please prepare and send us a simple project, with which we can reproduce the problem?
Kind regards,

I think I know how to generate the error. As long as my page post back to itself and once after it finished reloaded and then moved out from the current page to another page. Those errors raise. Please try on your end and see if it happens. Please help if you know how to fix the javascript error.
Now I have to do redirect instead of postback in order to avoid javascript error.
