I don't share files with other IDs, so I can't tell you if this is expected behavior or not for the Live Mesh bar that is added to the Explorer window for Mesh folders. As for the "widget" I assume you mean the Live Mesh Notifier that appears when you click the Live Mesh icon in the system tray.
You may want to submit a bug report:
How to Submit Bugs and Live Mesh Logs
Note that you may not receive a response to the bug report, though. It will be transferred to the internal system to be assigned to the appropriate development group.
