I have the following installed:
ZoneAlarm Free Firewall version: 12.0.104.000
Vsmon version: 12.0.104.000
Driver version: 12.0.102.000

I have windows 8.1installed.
I have a Dell m3800 it has a very high resolution and so the DPI needs to be set very high. This is causing the popups to appear off screen. Skype and other tools can handle this so I know that this can be solved.
This is incredibly annoying as it means that you have to change the dpi to set the popup and then change back again. Hardly a great user experience.
