A few users are experiencing strange network traffic from UDP Messagine. They notice it on other devices connected to the network. In some setups, it can even cause you to have cable TV interruptions.

Could have something to do with Routers that aren't handling multicast correctly.

Steps to Reproduce

No local repro yet, but MaxP has obtained the same model router as the user. So, in theory, this is the repro:

1. Connect NVG589 to your modem and PC
2. Connect a few other devices to the router (phone, roku, smart TV, etc)
3. Launch the editor on your PC

Result: There is suddenly network traffic on all devices and there is a significant decrease in bandwidth allocated to other devices (streaming becomes low res or choppy, speeds are slowed, etc)
