Hi,

That error message is the friendly maintain scrollback position routine. It is possible that your standard ASP.NET JavaScript files weren't properly downloaded to the page by the client. In case of using your own java script code, please check if JS code is correct. It may be caused by some corrupt line in code file.

Can you try to run appropriate page in different browser than IE? E.g. Firefox or Opera. It is possible that IE is more sensitive in Java Script compile process.

Another possible cause of this issue may be, if you have inserted some <form> element to page while using FCKEditor. It is because it´s not possible to have <form> element in another <form> element and FCKeditor generates one <form> automaticly.

In meantime, you can disable MaintainScrollPositionOnPostBack property, which should be located in appropriate .aspx file.

Best regards,
Vita Janecek
