Yes, simple TCP communications.

I don't think so. Except maybe the control itself. You know like the
explorer does when you navigate through folders (a soft 'klick').

Do you have a software firewall installed? Maybe that one locks up -
such firewalls usually have some driver-like code and digg deep into the
system. That would explain why TSVN is mostly affected: Subversion uses
some special http commands which might confuse a firewall.

Could be. But plink is a normal app too, running in user space. So in
that case I would suspect a conflict with encryption (firewall? driver
using OpenSSL/SSH dlls).

If you call Dell support, you have to climb your way up from the guys
dealing with people forgetting to plug connectors in the sockets to the
guys who know the real stuff. That's not easy if sometimes impossible.
And problems with drivers are serious, I don't think you can get that
high up in their 'telephone-chain' :)
