Lost Connection to Powerbox-Redux

This seems to be an issue that was part of an old driver. Seemingly, updating drivers to “some version” that is not clear to me (sorry I don’t have this equipment) will rectify the issue. The problem seems to stem from an issue in the driver you are using that issues UI notifications like the one you are seeing instead of allowing the controlling client (SGPro) to manage it.

This one mentions updating, but is not specific:

Keep getting popups for Pegasus Astro Powerbox - Premium Support - Main Sequence Software (sequencegeneratorpro.com)

This one mentions some possible cleanup required when switching versions:

In any case, Pegasus should be able to help you locate the version of that driver that does NOT issue the UI notifications.
