Thin clients on terminal services?

Is anyone else running spark on a thin client network using terminal sevices?

whenever a user gets an update notification and clicks ok the spark on their remote session is screwed until i kick everyone off spark and install update on terminal servers( running 2 as network is on 2 locations but using a single ADC)…is there a way to stop these notifications and allow me to decide when i upgrade?

It is a nice messenger though, i just need to control the upgrade.
