GUI FileDialog is glitchy

I am using some of the examples from the Python repository. . I have Open3D 0.13.0 running on Windows 10. The FileDialog is very glitchy. Id doesn’t display all of my drives (no-USB). Also, when I click Cancel and then re-open the dialog there are no folders displayed.

The GUI seems very useful and I am glad I found it. I am just starting to learn where things are in Open3D so It might be just a noob problem.

Is there a parameter to set to make this work more like a Windows FileDialog?
