Hi, I'm using version 4.61.1.83 (I've applied the lastest hotfix). When I do a post back (pressing a button or changing a drop down) something strange happens with my my URL (I'm not sure if this was the case before I've applied the hotfix): (Friendly URLs are enabled in the web.config) private void Page_Load(object sender, System.EventArgs e) { Response.Write (Request.Url); }

On the page Load the result is (the Friendly URL looks ok in the Address section of MS Explorer): http://localhost/developmentGateway/templates/GW_PageNotFound.aspx?id=1304&epslanguage=EN When pressing the button a few times I get this response : http://localhost/developmentGateway/templates/GW_PageNotFound.aspx?id=1304&epslanguage=EN&epslanguage=EN http://localhost/developmentGateway/templates/GW_PageNotFound.aspx?id=1304&epslanguage=EN&epslanguage=EN,EN http://localhost/developmentGateway/templates/GW_PageNotFound.aspx?id=1304&epslanguage=EN&epslanguage=EN,EN,EN Thanks, Danie
