Hi Vivienne,

I have not actually looked at the website but from your description it 
sounds to me that other Success Criteria than SC 2.1.2 may be relevant:
  - SC 1.1.1 for the text alternatives on the buttons
  - SC 2.4.4 and SC 2.4.9 for the link text (purpose)
  - SC 3.2.2 for changing the context without warning

A discussion of this is probably better on the WAI Interest Group (IG) 
mailing list, which I hope everyone in this list is tracking too:
  - <http://www.w3.org/WAI/IG/>

Having said that, I guess some key take aways for this group include:
  - evaluators need better guidance on the Techniques level
  - one issue often maps to more than one Success Criterion

We need to be aware of that, in particular the second point which will 
impact how we aggregate issues and score the websites. Is it a bigger 
issue because it maps to more than one criterion and thus probably 
impacts more people, or is that an artifact of how WCAG is structured?

Some of this may be partially answered through the RDWG Symposium:
  - <http://www.w3.org/WAI/RD/2011/metrics/>

The first point may indicate that a "How to Evaluate WCAG 2.0" rather 
than "How to Meet WCAG 2.0" quick reference guide is needed:
  - <http://www.w3.org/WAI/WCAG20/quickref/>

We will need a lot more discussion about how this guide is to look like 
but it is one of the planned activities:
  - <http://www.w3.org/WAI/ER/2011/eval/#supporting>

Are there other particular issues that you wanted to raise?

Sidenote: this seems related to a previous thread from Detlev Fischer:

The person using a screen reader would not know they have entered a new window unless they hear and notice the new URL, but that's not what I'm wondering about.  The only way I can see to get out is to exit the window via the Alt-F, exit option to close the window, at which time you go back to the starting point.  My question is, does this constitute a keyboard trap?  For example, the user doesn't know they are in a new window, so would not know to exit in the above way.
