[carmichaelong]

Steps to reproduce

1. Open a model
2. Open Static Optimization Tool
3. Click the folder icon under Output -> Directory

Expected result

Title says something like "Choose output directory"

Actual result

Title of dialog box says "Opensim model (.osim)" (or sometimes some other title). Also, the file type chooser shows .osim, but it should highlight that a directory should be chosen.

Environment and GUI version
