When a user minimises or maximises a citrix session the colour is degraded to 8 bit from 16 bit. This cannot be changed within the current session but is reset back to 16 bit once the users logs out and back in again. There are currently 3 Citrix servers in our organisation and all use the same settings and policies and the problem only occurs for users connected to the latest Citrix server. The user connects to the Citrix server through a WAN via a 1Mb connection using the latest ICA client V10.1. For comparison, when I open a session from each citrix server, only the session from the latest Citrix server degrades the colour depth when minimising and maximising. I have searched the Citrix knowledge base for answers but to no avail. I would appreciate any help on this subject.
