I've had a trawl round the net but can't find anything about this. the 
message I get from Firefox is :-

Download this potentially unsafe file?

File Type: “ASP.NET Document”.

It is unsafe to open “ijb.aspx” as it could potentially damage your 
documents or invade your privacy. You can download it instead.
