Protecting your action

[ThinkQuick]

1/2 No limit dealer's choice.
I have folded UTG.

There is a raise to $10, called by the woman in seat 10, after her there is a reraise to $20 by LP, called by CO and Button.
Then BB reraises to $60 (capping the action).

The orginal raiser folds, seat 10 is holding her cards in her hands and staring at them, long enough for LP, CO, and Button to all call the 60 (they must not have noticed her).
Seat10 then asks "is it capped?", dealer says yes, she calls, and the flop is dealt.

Does she have an obligation to protect her action?
What is the status of her hand after waiting to see the 3 remaining players all act (not too speedily I might add)?
There might be a case that she didn't notice.. but does that even matter?
