HUDs in noscript areas

What's the trick to get HUDs to continue to function when you enter a noscript area? I'm trying to bring up a llDialog upon touch, but it won't work in no script areas. The event gets queued because the dialog comes up once I leave the area. I've read that scripts continue to function if they've been started elsewhere, but that obviously isn't the case. Someone mentioned using the llPassTouches but I can't get that to work either.

I have a couple of HUDs that continue functioning in noscript areas so I know it's possible. These are not bringing up a dialog however, but have their own set up buttons.

I think you just need to request controls permissions then call llTakeControls..

Thanks. That works!
