When people say they know what I did it reply "all right, you do it then" and hand them the deck or whatever (also works great for "Oh I seen this one") usually shuts them up for the duration of the effect.
However, if it happened once, it can happen again. I say get a better force. Let this be a learning experience.
My usual replies in these situations:
Spec: "I saw that"/"I know what you did"
Me: "Don't tell me! I don't want to know!"
Spec: "You did something" or my favorite "You flipped it!!"
Me: "I know... I was there..."
I think everyone know's i did "something" obviously because it is a trick.
I would however practice a bit more and work on making things invisible. It sure helped me. Next time do some sort of trick in their hands- i prefer search and destro by aaron fisher. It really grills them and gets you away from the trick a bit.The artist formerly known as... Vintageillusion
Thanks for your help everyone. These things happen from time to time, especially when your experimenting with a new routine. Those are some great lines, all of you. Timing and misdirection could do a lot, in this instance it would have been difficult, she was sitting down behind me to my right at the worst possible angle for a top change and I didn't really realize she was watching until it was a little too late.
Lots of good ideas though guys.
Anytime when a spectator tries to call me out on something when i'm doing strolling, I usually just play around with them. It's nothing to blow up about, even if they guess wrong. Just finish performing that trick and either move on to something that will fry them or just thank them for their time and go onto the next group.
If she was ruining the rest of the trick as you were performing, I'd just turn to her, put my finger over my lips and tell her to shush and give a wink(being friendly, not rude). This way she thinks she's in on the trick and remains quiet throughout the rest of the performance.White Centurions

Ortiz talks about this in his book Strong Magic.
It doesn't matter how much they saw, even just a suspicion, and they will feel like they know your secrets. This is motivation for the magician to carefully think through, not simply the sleight of hand, but each movement we make.
When I think someone really did see something they shouldn't have, I will reply to their "I saw what you did!" with a sly smile and "but you'll keep it a secret too." I say it in a now-your-in-the-club sort of way. Works very well.
This happened to me yesterday, I performed for 3 people. the problem began when I did a DMB control, it was invisible for 2 of the spectators and I'm pretty sure that for the third one too, however he claimed that the outjogged card wasn't the card he picked. I guess this happened because he has a little knowledge of magic and knows that sleight of hand is present in most impromptu tricks.
Anyways, I ignored him completely. Surprisingly the other 2 spectators supported my attitude and even told the heckler to shut up. In the end I modified the effect I was performing and turned to a mentalism effect. I got awesome reactions.
