I have a single policy assigned to users XXX and YYY. Both users (i.e. the ZESM agent on their workstations) have already downloaded the policy.

1. I modify the policy
2. I re-publish the policy for XXX only (i.e. not for YYY)
3. on both workstations, I right-click the ZESM tray icon and choose "Check for Policy Update" from the menu
4. for XXX, the changed policy is downloaded (tray message: "Your client policy has been updated")
- this is what I have expected
5. for YYY, the changed policy is not downloaded (tray message: "No policy update is available at this time")
- why?

So in short: how can I force -- manually -- a modified policy to download immediately without re-publishing it?
