Since we added 2 new Imacs to our network last week, anytime we double click on a file, it makes a copy...if you double click on the copy it opens up. If you drag file to the Quark icon, it opens OK, but you can only do 1 save, then you have to do Save as because you get "unexpected end of file encountered". We have a simple network that assigns IP addresses to those things on the network if that helps. Any ideas?? Oh yea, new imacs are running Leopard and we are still using Quark 6.5 on them...one has 7.1 loaded, but it has the same problems.
