after upgrading a few agents to 10.3 I found the "HonorClient32WorkstationOnlyCheckbox" key didn't work anymore - of course...the keys got a change.. :)

So - I had a bundle to set the key value, thought it would be a good idea to just extend it: added the new key/value and assigned it to all workstations (so both keys get applied).
I was in hope it would make things better as the key would already be present before upgrading the agent....but now I got hit: The 10.2.2 agents stopped to login automatically to ZCM, so ATM I'm forced to upgrade all agents faster than scheduled...

Good thing about it: 10.3 seems to solve some annyoing problems, hopefully I can workaround the few I should expect ;)
