[cs3/as2] Strange problem with combo


I’ve got a very strange problem with combo box. I have created a movie clip and onPress a combo under the movie clip shows or hides. It works very well until the combo box was used. If you change the value in the combo box the movie clip accepts only the first click and doesn’t react on the next click until the mouse is moved at least a pixel. Can you suggest me how I can fix this annoying problem?

Best regards,
