"When she is not talking she is rummaging through her pocketbook, whispering to the person seated next to her, etc. "
you may have done that, but to you approve of your behavior back then? do you feel your behavior back then was acceptable?
I wouldn't see anything wrong with taking her aside and talkin about her actions during the meeting.
as far as the personal problems being shared at meetings, the 2nd part of yer thread starter comes to mind.
but to start with- ask her if she wants to get sober and is willing to go to any lengths.
