Thanks for that, I realise that the load on the server will always play a big part in affecting the build time but once the build time has gone up, I never get another build that only takes a few minutes.

I still can't understand why the build time was reduced to a few minutes when the project was moved and moved back again. I was beginning to think that Fox might store something somewhere to do with paths and that, when it informs that the project has been moved and gives the option to make the new location its home directory, it might restate some of the files this speeding up the rebuild.

Thanks again for the reply.
