There is an error in the latest version (and probably all versions of TLA) in the logged-in user component.
TLA reports that the user running TLA is the person logged in on the remote computer. This is known to at least affect Vista, and possibly XP.
I believe it’s due to the fast-user switching. I’ll have to research it.
In short, don’t be alarmed if you see your name show up as logged in to the remote computer:)
