SIS 5.12.1 upgrade from SIS 5.11.1 - not seeing water-column data

[kvonkrusenstiernOX]

Recently upgraded EM304 and EM712 from SIS 5.11.1 to SIS 5.12.1.

When going through my sanity checklist to ensure full functionality for data acquisition and processing, I noticed that there was no data in the water column display. This occurs on both EM712 and EM304. I tried the following troubleshooting steps:

1. Restart software
2. geographical restart (separate icon on desktop)
3. SIS User Interface Restart found in the SIS Software
4. Exiting out of the Water Column Display and then bringing back into view
5. Rebooting PU.

Because this is happening to both sonars, I am thinking there is a bug related to the software. I've reached out to Kongsberg for insight..
