I am a new user of SD 2007. I use it to make sales maps and created one using a sales map template. It worked great except the state of TX is giving me problems?? I can't select it to make changes. All the other states are not giving me any problems. I can't find any troubleshooting tips in the help section. It's almost like when it is shrunk to a certain size, you can't select it anymore to make changes???
