I am trying to open PCBDOC in CS version 1.4 that was originally created in Designer 14.3. I converted the file to PCB 5.0 Binary. However, I am getting a ugly outcome in CS. When I open the PCBDOC in CS, CS will open a seemingly infinite number of instantiations of CS (i.e. multiple windows). The only way to stop it is to shut my computer down and restart. Has anyone else experienced this?
