As of couple a days ago my Live Mesh client at home is going nuts. It is constantly uploading something. The funny thing is that the tray icon does not indicate any activity. NetLimiter Monitor also does not show any activity per processes running but the wireless traffic indicator points that there is something being uploaded all the time. Looking at the logs does not reveal anything.
I can not uninstall the Mesh client. I removed the client manually, according to the instructions in the Known Issues post but without any differences in behavior after the new installation (with UAC turned back on).
Also, since the only installation package available for download is build 14, I can not install it with UAC turned off.
