For a long time, we users have been promised the ability to switch off the automatic dumping of the recycle bin by SupportAssist, but it never materialized.  I've given up on that battle.  But if SupportAssist MUST dump the recycle bin, could it possibly be programmed to also refresh the desktop in the process, to make it readily apparent that it has done so?  Currently, the icon doesn't change into the empty container until a refresh or reboot.
