After updating to 10.3.1 agent, the ZENworks Window is missing all
icons. Not all desktops experiencing the issue but a lot of have
reported the problem. Refreshing the agent some times work. Some
times we have to issue commmands

zac cc
zac ref general bypasschace

And worst case we have to uninstall, reinstall the agent to get to
work. Anyone see this, is it a known issue?
