Here's a strange thing...

I have an ordinairy base class list box with a SQL row source. I have one method in the interactive change which updates a form property with a value from the select, also this property is an assign method.

However the strange this is...

You can drag items in the list on to other items in the list, I haven't enabled this it just happens. This then causes an error apparently due to the primary index being violated!

Any ideas why?

Help greatly appreciated, thanks.
