A user control contains a tabcontainer. When aspx page loads, the user control is not visible. Ajax toolkit script function tries to set focus on tabcontainer and it throws exception : "Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."
The problem occurs in IE 8 with 11/16/2011 release. It worked OK with sept. release.
Comments: woodburyk is right. This issue should not be closed. I have updated the dll in http://ajaxcontroltoolkit.codeplex.com/workitem/27201
