Response from the Working Group
================================
RE: Issue 1:  It is often true that an action or practice will cause more
than one SC to be violated.  The fact that something fails SC 3.2.2 does not
mean that it would not also fail SC 3.2.5 or be discussed there and vice
versa.

However, you are correct that we should go further in "Understanding SC
3.2.5".  So we have added to the end of the sentence so that it reads

"This Success Criterion aims to eliminate potential confusion that may be
caused by unexpected changes of context such as automatic launching of new
windows, automatic submission of forms after selecting an item from a list,
or changing the content on the page simply because the person navigated to a
section but did not select any link or button or issue any command other
than navigation. "


RE: Issue 2:

People working toward level A conformance need to see this in SC 3.2.2 and
will not be looking at SC 3.2.5.  Opening a new window is a change of
context and is therefore covered under SC 3.2.2.
