Restoring focus to a text input box

Hi guys,

I was wondering if there is any way of restoring focus to a text input box, or alternatively, stop the text box losing focus altogether?

I have a slide that shows a layer containing the aforementioned text input box. As soon as this layer is shown, focus shifts to the text box and the cursor within it starts flashing. Great stuff. The only problem is, when the user clicks on anything else on the screen, focus is lost and the cursor disappears. I want to get it so that the cursor is constantly flashing in the text box i.e. focus never leaves the input box.

Is there any way of achieving this? Maybe through some javascript trickery perhaps?

Thanks in advance,

Andy
