Hi Beth,

I also had issues with topshim last summer on my AVIII (TS 3.6.5). Not identical
to your descriptions, but symptom severity clearly followed sample quality and
solvent choice. Discussions arrived at a similar hypthesis of poor sino during
topshim scans. In my case recent hardware tinkering had affected the deuterium
pulsewidth. Recalibrating the 2H 90 immediately brought topshim back to normal
behavior.

Kind regards,
Luke
