I sort of fixed this error by moving the calls to 
promptService.confirm() and promptService.confirmEX() into a new JS 
function called doAsk(). I did this because I found out that using 
aWindow.setTimout(doAsk,0) is a way of preventing the error, because it 
than runs in the context of aWindow, but I can't use that.

The main reason for this is that I need the return values from 
promptService.confirm() and promptService.confirmEX() and I don't know 
how to solve that problem...so I've still a lot to learn, and can use 
some help.

Is there another way to run doAsk() in the context of aWindow, without 
using a aWindow.setTimeout? aWindow.doAsk() didn't work, or I did 
something wrong, so... HELP !!!
