no change after trying re-install.
i also get this happening when i press on a link not everytime though
the webpage code i presume.
(function(n){function v(){n("#InsertMenu").off("click",v),f=t.setTimeout($CC(t.AttachmentUpload$onUploadControlError,[null,{errorMessage:"load timeout"}]),s.UploadControl.LoadTimeout)}function
