Comment 2 for bug 682744

Chris,

Unfortunatly Windows does not provide an easy way for you to know what the different processes of the app are doing. I recommend you to install Process explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) and get information about the UbuntuOneClient.exe process as well as the child process that it starts (called main.exe) which is the process used to perform the sync.

With that information we will be able to get closer to fix this issue.
