Windows Forms open and save default directories

Question

I'm editing someone else's code that uses Windows Forms:

SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.InitialDirectory = LevelEditorConstants.PATH_TO_DATA_DIR;

Somehow, the directory that opens is totally different than the constant value that is assigned to it. How else can this value be set? A text search for a string that is part of the path that does open turns up nothing in my entire solution.

UPDATE: After attempting to save a file in the correct location (navigating there manually), and having it throw an exception for unrelated reasons, the problem is solved. I have no idea why.
