Yes, you are correct. What I am trying to do is a modal dialog. My page
has a form that is updated by user interaction. If the user tries to
move on without save the data, I want to pop a modal dialog with a SAVE
and CONTINUE button. The SAVE button saves the data and both buttons
dismiss the dialog. While the dialog is up, I need the UI blocked.
So the simple test case works great, but if I call it directly is does
not wait to be dismissed.

Thanks, I noticed the empty() but didn't pickup on the side effect.
