Drag Drop elements scroll up, but not down?

[joergd]

Hi,

I have a div that contains many DDProxy items, that span way beyond a single page. I can drag an item to the top edge of the screen, and my page scrolls. But dragging it to the bottom of the page doesn't scroll the page. Where is this behaviour 'controlled'?

I implemented the classic YUI sortable list example, using Ext. I basically copied this example - given by somebody else on this forum:

(If you add several more slots to the screen, so that they start overflowing, you'll see that the scrolling doesn't work.)

Any ideas?

Thanks
Joerg
