I built a custom step types in Teststand Type Pallete. This step type called a DLL(Embedded a UIR file as step type's user interface) in Post and Edit steps and exchanged the values between this DLL and Teststand GlobalFiles.I inserted one step in my client sequence file and saved it. My question is everytime I changed the configuration on that step's user interface, and closed this sequence file, Teststand would not ask me to save it.(Teststand should asked me to save it, I think). Why?
