Modifying settings

[NajaWulff]

Testing the settings feature consists mainly of making sure that all the pre-set options are registered when clicked, and that they still exist between loggins on and loggins off.

Assumption: In context of the guest logon, changes should not persist between sessions.

Borderline cases:

1. Log on, change background colour, etc and play a book, checking that the changes are registered.
2. Log out again, log on and check that the changes still persist
3. Log on as a guest, change background colour, text size, and font, play a book.
4. Log out, log on as guest again and check that the changes are not registered,

To problems occurred while testing the settings. 

1. When changing the settings while logged on as a guest the changes remain.
2. When changing the settings in IE9 the screen freezes.  

Conclusion
As it turns out the first problem described above is not a problem. Nothing else to report.
