Disabling text fields

Okay I’m going to try and explain this best I can. Don’t want to post the fla cus it’s too big i think.

I have a button on my main timeline that pops up a mc on the stage like a popup window. That popup window has some dynamic textfields in it that have xml data. Well I have a close button for it that alpha’s it down, the problem is that the text fields get in the way of the buttons underneath it. So the textfields have 0 alpha, but are still selectable and stop the onRollovers for my main navigation. Any way to fix that? I know I could probaly just set the position to off the stage after it alpha’s down. Any other ideas?
