memory-leaks

I have an ItemsControl that uses a DataTemplate to display properties in my customClass that implements INotifyPropertyChanged...

Pretty straightforward...

Some items in the DataTemplate use CommandBindings (such as buttons), and a few have some code-behind (yuck).

When I empty the ItemsControl and set all instances of customClass = Nothing , no memory is released from my program. This becomes a problem pretty quickly!

Any idea where I should start looking? I've even gone so far as to completely traverse the visual tree of each DataTemplate instance and set each Visual = Nothing. I'm not really if that's supposed to have any effect though.
