    There's a very basic error in the latest RadToolbar release. If your client-side OnClientButtonClicked handler calls alert() or confirm() when a drop down button has been clicked, you'll get the following javascript error when using IE8 (doesn't happen in other browsers):

    Line: 5012
    Error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus. Example handler:

            function Toolbar_Clicked(sender, args)
                var button = args.get_item();
                var command = button.get_commandName();
                switch (command)
                    case "RESOLVE": // command for button in toolbar drop down
                        alert("This message box will cause the javascript error once it has been dismissed.");

    There is a workaround - if I do the same functionality on a different thread (e.g. calling window.setTimeout(myfuncthatcallsalert, 5)), all is well.

    Is this a known issue? Fixed anytime soon?
