Since moving to El Capitan from Mavericks I've had an odd little problem when trying to open files from within my grading program (Making the Grade). In the past, when I would hit Command-O to open a new file, the last-opened folder would appear. This was generally my Grades folder. However, now that I started using El Capitan, I see the Grades folder momentarily, then the dialog box suddenly switches to the Documents folder. This is a bit annoying. Is there some way prevent the Documents folder from being the default for opening my files?
