Hi Peter,

It may be related to the axd setting on the servers - you can easily check if this is the case by modifying the image acquisition mode of the control:

1. In the code change the image acquisition:

NDrawingView1.ImageAcquisitionMode = Nevron.UI.WebForm.Controls.ClientSideImageAcquisitionMode.TempFile;

2. Create a directory called NevronTemp in the root folder of your website - for example (C:\Temp\WebSite2\NevronTemp if the web site is located at C:\Temp\WebSite2\).

3. Give this folder read, write, modify permissions to the ASP.NET account.

Hope this helps - let me know if the problem persists.

Best regards,
Bob
