Drag input text field

hi all
i m designing a movie in flash that dynamically generates the text boxes on runtime according to the number written in the external xml file. the end user can drag the text boxes and can set its new location. the problem is when i put the input text box in a movie clip, for dragging purpose, i m unable to enter text within. because when i press the text box its start dragging and the cursor not appears in the trextbox.

thanks for any support.
