I went ahead and added two new QuizPort config settings for frames which you can modify via the Site administration -> Activities -> QuizPort page.
- Frame height (default = 85)
When a quiz is displayed within a frame, this value is the height (in pixels) of the top frame which contains the Moodle navigation bar.
- Lock frame (default = No)
If this setting is enabled, then the navagation frame, if used, will be locked so that it is not scrollable, not resizable and has no border
