Pause when dragging dockable windows in VS2005

[Weeble]

Whenever I drag a window that is in the "dockable" state by its title-
bar, Visual Studio locks up for several seconds before the window
starts moving. Then, even if I've already let go of the mouse button,
the window leaps to the current mouse position (not the position where
I let go). I've started Visual Studio in safe mode and not loaded any
solution and it still has a pause of about two seconds. Under normal
use it can be around six seconds. Other developers here say they have
not observed this behaviour, and I'm not sure what could be causing
it. The CPU is not under particular load. Any advice for diagnosing
the problem would be appreciated. Note that it is only "dockable"
windows that suffer from this: "floating" windows are perfectly
responsive.

System: Pentium 4 650 3.4GHz (hyperthreaded), 2GB RAM, XP Pro SP2,
nVidia GeForce 6800
Other software: Sophos Antivirus, P4SCC (Perforce source-control
integration), Visual Assist X

I found the problem: NVIDIA's NView. I discovered that during the
pauses it's filling up the system application log with errors. I think
it's leaking some sort of GUI-related memory, but I don't really know
how the Windows GUI works, so I don't quite understand. The post by
"welie" on this page seems to describe the problem:

I don't know if there's a fix for this, but the workaround is to go to
the NView control panel and disable NView. It doesn't do anything
critical, it just helps you organise windows on multiple desktops.
