ORD Properties Menu "no content to display"

Hi there, I'm using OpenRoads Designer. For some reason, when I have the properties menu docked it'll be working just fine. However, if I leave the properties palette docked and open a different .DGN, the properties menu will then display "no content to display" when I select an element to display the properties of. I've tried to close the pallet and re-open the properties menu, as well as docking the menu to all a bunch of locations on the screen, and lastly un-docking the menu altogether. It seems that no matter what, the same message displays no matter what type of element I select (include referenced objects).

Does anyone have a fix for this? I just have to close ORD and re-launch the software, but I'd rather not have to do that every time I want to switch between files. 

Thanks in advance!
