Once I have opened an assembly off the network in SW, does SW still keep refering back to the network while I am working on the assembly? It just seems as if I have the same assembly open but have it on my local machine, the file is easier to work with. If I open it off the network, in time it will gradually get slower and harder to work with. Any reasons for this? It may the same question as my previous post but I have try and get a handle on this soon. It is driving us crazy.
