listcollectionview

My case:

MVVM
ListView+Details(custom UserControl)
List bound to MV.Items (IsSynchronizedWithCurrent=true)
Details bound to MV.Items.Current
MV.Items.Count == 100
about 0.2sec to read details (lazy mode)

When I hold the down arrow on the list, very strange things happen:

list items order change
current changes in the random order
CPU usage drastically increments and eventually all hangs.

I've read some post that one should start the timer or run handler in the background, but I am not able to do that, since all the binding WPF does for me.

Is there some way to instruct the binding in my DetailsControl, to wait a while before accepting CurrentItem? Or should I just resign from the clean solution and write custom code in my MV to handle that?
