Can you send a debug level 10 log of this, also how is the client doing
this mode ? Via explorer ? I don't have access to a Windows XP box at
the moment (travelling). I'll be back home with access to my vmware
sessions on thursday.

Sounds like a bug but I'd like to reproduce it and check it's fixed
in 3.0.21 (might be the delete on close issue that got fixed...).
