Folks, I researched the order-of-precedence that Pro/E uses to retrive config files.
To the best of my memory, the first place Pro/E looks is in your root directory. It then looks in the bin directory. It adds the settings together as it reads all config.pro files. In the event of a conflict, the bin version prevails. However, as already described, you can use the Utility Menu to select a config.pro that is in your working directory to over ride all other config.pro files.
If you have a config.sup file, however, its settings will over ride any config.pro setttings regardless of where they reside.
Hope this helps. You may want to check the order of preference, though. I suspect it is more complicated than I described above.
