Why Could I see my File Transfer Window?

I sent a 6gb 7z file from my home office to the corp. office. I left the factory. When I got on my home docking station the File Transfer window was no where to be seen. The connection was still live to my engineering workstation but there was no record available that I could find confirming the status of the transfer. I've use TmVwr since it's inception. I know well beyond the basics. There was no indication of an active transfer. I chose the close connection command and there was no warning or query of intent. Once closed the log window popped up showing "File Transfer Finished". Bull shit. The Transfer Window was open on my home office computer when viewed from my workstation. WTF was it when I got home?
