We have a customer that is an all Mac environment and only 2 Macs are experiencing issues with 2-way communication. On both of them when they select 2-way communication and hit Full Properties whatever application they are in (doesn't matter what app we have tested with many) will freezes up and a force quit is needed. They are running 10.6.8 Snow Leopard and other Snow Leopard machines are not experiencing the issue. No firewall involved, can get to the web interface and such of the copier, and it will print so it seems to communicate fine. In the driver it will even show the Toner Levels so SNMP communication is working. Does anyone have any ideas?

Note: We have uninstalled and reinstalled multiple times both with and without the Fiery Software Removal Tool.
