I can't see it's implementing IDisposable at all, at least there's no
method "Dispose" also in the "big" fx.

I now close the stream as well as the response, as shown below:

WebRequest req = WebRequest.Create(strURL);
WebResponse resp = req.GetResponse();
using (StreamReader reader = new StreamReader
                        (resp.GetResponseStream(), System.Text.Encoding.UTF7))
{
        strResult = reader.ReadToEnd();
        reader.Close();
}
resp.Close();

...but there's still the same error. :-( I begin to wonder whether we
work with a beta release of CF... :-/

However, in another thread on this NG I found a link where a download of
a file is being described:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/AutoUpdater.asp

I try this out and hope it helps. If not, I thought to just catch but
ignore this exception (currently the user would get annoyed by a dialog
box saying that the transfer failed - I will make a routine around the
call that tries it maximum three times automatically if the problem
persists).

Best regards,

Michael
