Hi Greg,
The book mentioned the issue re fiddler with supporting localhost (with IE) – but the latest version worked for me straight out of the box. It’s interesting to watch what packets are going on your machine (more like scary). *Regards,* *Steven Parish* *Software Architect | BusinessCraft Pty Ltd | www.businesscraft.com <www.businesscraft.com>* Tel: (02) 4965 5555 | Mob: 0417 688 599 | Fax: (02) 4965 5333 | Level 1, 270 Turton Road, New Lambton, NSW 2305 ------------------------------ *Disclaimer* The information contained in this and associated e-mails and any attachments are confidential and were only intended solely for the use of the addressee.

Any breakpoints you set will be hit. I am pretty sure that this has worked for me. I'll try that, and I have to install a fresh Fiddler on my new system anyway. I remember last time I had to jump through hoops to get Fiddler to work with localhost, but maybe that's easier now -- Greg
