Reference files do not appear in OPR

The Fit View tool has the option for "Reference", which should zoom the window to where your references are. Does that help?
Another thing to check is that you have the correct model of your reference DGNS attached. if the model attached is empty, there will not be anything to display.
Another couple of items would be to make sure that the levels are turned on for your references, and to see if the view attributes for "Constructions" is turned on. I have seen both things show "nothing".

This is my issue....

The reference files will load and all the levels are on but I do not see the .dgn   It might be due to the reference files being used are SELECT 4 Series and I'm using a newer version of Open Roads that's not compatible???????

The linework should still be visible even if the file is read-only, unless the file can't be found. In that case, however, it would be red, not black, in the reference dialog.

Are the references already attached? or are you trying to attach them? If the file is read-only, you probably can't attach references, and it would be a bug for it to "pretend" that you can.
