[JD-]

Running on IPad simulator with the Elements tab of the Chrome Developer opened.

Showing a UIAlertView, I get an NSRangeException.

The exception occurs at line 531 in PPDOMDomainController.m
UIWindow *previousWindow = [windows objectAtIndex:indexOfWindow - 1];

As a quick fix, I have replaced

 if (indexOfWindow > 0) { 

by

 if (indexOfWindow > 0 && indexOfWindow != NSNotFound) {

but I think there must be some more complex work to do as it possibly affects a feature.
