Hi Mark,

I had a look at what is going on with Fiddler and each time the parent drop down is changed there is a single request which returns an http 502 with the following message:

DNS Lookup for "_vti_bin" failed. The requested name is valid, but no data of the requested type was found.

Is that something you have seen before or have any ideas about how I can resolve it?

Thanks,

Aidan
