Hi Both, Richard, I think your suggestions about the service providers restricting access might be what I'm experiencing, because this only seems to affect my primary PC. When I try on another PC there's no issue and all layers load first time without a hitch! I've also tried adjusting my timeout for network requests to 30 seconds (30000ms), but that doesn't help. Might be a problem I have to put up with, but it's really frustrating. I wonder if there is a way of refreshing my IP whenever it gets too difficult to load these layers!!? Nigel
