Right now I have Popup Blocker enabled for the lockscreen, and it's working great. I've got SMS alerts allowed in the PB settings, but didn't touch anything in the "Exceptions" section. So basically Messages+ is just using the native SMS settings, but the popup gives me Messages+ Quick Reply when I use the Slide to Reply option. Everything else is blocked at the Lockscreen. (You can see below that I got a statusbar icon for my email, but I didn't get a LS popup for that, only for the SMS. You can, however, set it to wake the LS when an alert is blocked, which is what I think you wanted, right?)
