My code is knee deep in retrieving prim and texture info including detailed properties using the "selectobject" method. Prior to today's release, I would log out, and no problems, now the above exception (null reference) is thrown in the private void Client_UploadDataCompleted(object sender, CapsBase.UploadDataCompletedEventArgs e) method under eventqueue.cs module in the last line of the following code... if (e.Error != null) { HttpStatusCode code = HttpStatusCode.OK; if (e.Error is WebException) code = ((HttpWebResponse)((WebException)e.Error).Response).StatusCode; the webexception object is not null, but the response field evidentally is. hope this helps.
