Growing. 1 report or thumbs-up in the last 7 days and none the week before, down from 2 a week at the late-October peak. A workaround is known.

Mouse wheel sends arrow keys in sessions opened from Agents view. Wheel cycles prompt history instead of scrolling the conversation in attached sessions; PgUp/PgDn work and sessions started the normal way scroll fine.
