sorry, ill make it clearer. it was hosted on a server within our development office whilst it was being created. Once finished it was moved to our clients offices and installed on their server. Both running the same version of FMS, once in the new office it is unbelievbly slow, taking as said around 10 mins just to open up the define relationships box. our clients systems are a much higher specification (network and server) than our own. hope that helps...
Ive got the same problem, about 30 files and as many relationships. The whole database became slow once moved from its development machine onto the server to host it. Dont know if the different IP addresses are the problem. have you found anything out?
