Hello,

We were trying to upgrade to a Telerik Dll version 2008.2.1001.20.

However we are facing strange issues. I was able to track one to a simple aspx file, that contains RadAjaxPanel, button, hyperlink and a tooltip inside of that panel. Tooltip is shown when you click on hyperlink.

Another one requirement is IE6.

So in the scenario that we have, if you simply click on a button, everything seems fine, but if you open and close a tooltip and then click the button, IE catches a JavaScript exception somewhere inside of destroyTree, while trying to redraw the panel. 

As a result no more javascripts are working and the content of the update panel is not refreshed.

The test page is included. Please help.

Hi Konstantin,

Indeed the error can be observed with the 2008.2.1001 version of the controls. However I just tested it with the Q3 Beta release which was announced recently and the problem did not appear. Please give that version a try and let us know if you find any issues with it.
