Flex popup manager, mousedown outside popup removes popup

Question

If you create a popup using:

PopUpManager.addPopUp (popup, this, false); PopUpManager.bringToFront (popup);

It will create a popup and display it on top of any other visual part. I have one problem. This popup should remain even when the user interacts with the background.

I would use modal, but I need the ability to interact with the back. Any way to tell the popup manager not to remove the popup when the user clicks on it?

Thank!
