Hi Bob,
We've received reports from other customers that Live Mesh will sometimes use an excessive amount of computer resources (CPU, memory). We're working to improve this, but if you could collect your Live Mesh logs (Start Menu > All Programs > Live Mesh > Collect Live Mesh Logs, which will generate a .cab on your desktop) and send them to
lmprev@microsoft.com, we can look into exactly what Live Mesh was doing (please include your forum handle, and the title of this forum thread in the body of the email, so that we can track the issue).
Thanks,
Ben.
