We are having a really strange and stupid sounding problem with a text input box. It appears but won't allow any input. Before you shout 'stupid newbie' yes the properties are correctly defined as input text etc.

The input field is in a movie clip i.e. _root.myClip but we have never had this problem before. It is probably something obvious to to prevent us pulling out all of our hair has anyone got any idea why this is happening. We have tried forcing the text box focus etc but to no avail.

Help us!!!!!!!
