When I list “[System]Client/Network/Hostname” in the read all, its value comes back as None, but when I list it in a seperate read call, it works fine? here is the script that actually worked:

tags = system.tag.readAll([  
“[Client]Monitors/MonitorCount”,  
“[Client]Monitors/Monitor1PosX”,"[Client]Monitors/Monitor1PosY"," [Client]Monitors/Monitor1SizeX","[Client]Monitors/Monitor1SizeY",  
“[Client]Monitors/Monitor2PosX”,"[Client]Monitors/Monitor2PosY","[Client]Monitors/Monitor2SizeX","[Client]Monitors/Monitor2SizeY",  
“[Client]Monitors/Monitor3PosX”,"[Client]Monitors/Monitor3PosY","[Client]Monitors/Monitor3SizeX","[Client]Monitors/Monitor3SizeY",  
“[Client]Monitors/Monitor4PosX”,"[Client]Monitors/Monitor4PosY","[Client]Monitors/Monitor4SizeX","[Client]Monitors/Monitor4SizeY"  
])  
values = [system.tag.read("[System]Client/Network/Hostname").value]  
for tag in tags:  
values.append(tag.value)

This issue with readAll() and client system tags is fixed in 7.7.5.
