Transfer from web to local shared drive freezes app

I use my desktop PC to run WinSCP. I am trying to take files from my online webserver and transfer them to a local shared drive (shared drive is hosted locally on a Win Server 2008 machine).

When I click and drag the file I want to transfer, WinSCP freezes for about 3-5 minutes, and then the file shows up where I wanted it to go.

What is causing this freeze up and delay? It is unworkable, and doesn't happen on Server 2003 machines, just the Server 2008 machine.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
