dribble out of bounds or not?

[johnyd]

GJrHi, I was trail in the back court. Long pass to the front court on my sideline. Defender tips the ball away, takes one dribble and loses control. As the ball is headed out of bounds at half court she leaps from inbounds smacks the ball into the back court. Her momentum carries her out of bounds. She runs down the side line out of bounds about 4 strides, comes back in bounds and picks up her dribble. No one else touches the ball. I blow it dead.
At half time my partner says that was a legal play and she had every right to pick up the dribble. What sayest though??
