Cannot Open Files

I don't know why, but all of a sudden, I cannot open files through the DraftSight application. Unless if I open File Explorer, go directly to the drawing I want to open, and open it, then I wouldn't be able to update any drawings.

Clicking the "Open..." button.

Cursor shows it's waiting for an input.

Command Window is waiting for a specified file.

I've tried typing in the full path and file name (C:\\[Folder Path]\\[File Name].dwg) which does open the file, but I don't want to have to type it for every file. I would hazard to guess that for some reason DraftSight isn't opening File Explore's Open window. What solution is recommended?
