Livemesh bugs and solutions

Livemesh is a good tools for synchronise folder and remote desktop. Today, I just found one bug of the livemesh. If I signout the livemesh of account1 and signin using account2 in which I didn't synchronise any folders, any update in the previous synchronised folder will STILL keep updated in other machine. In addition, the machine is still visible to others even though they are using different login account.

Solution:
The solution I get is to delete the machine with account2 in the online livemesh machine list. Then it will stop the synchronisation.
