dwg file location

I have just updated to Draftsight 2017 x64 SP1.

I now cannot change the location of my dwg files from the default Draftsight setting.

I have gone into Tools, Options, Drawing Support, Drawing Files location and changed the path to that where my files are located and OK'd it (the new path shows in the dialog box). But when I go to open a files it still takes me to C:\\Program Files\\Dassault Systemes\\Draftsight\\bin.

This worked fine on my previous version.

Any ideas?

Thanks
