I'm noticing some nuances after upgrading a couple of my servers to 5.2. If I connect to a server via Remote Desktop that has been upgraded to 5.2, I am unable to interact with the agent the same way I was with 5.1. For example, I am not able to right click on the tray icon to disable the security. I've done a rule comparison of the 5.1 and 5.2 agent UI rule, but I am not seeing any differences to warrant the behavior I'm seeing.
I have this problem too.
