Dirk vanWestrienen commented on RF-1100:
----------------------------------------

I noticed the same issue in both Firefox and IE.  Inability to drag an item to a location that wasn't currently visible in the view port.  We solved the issue by editing the footer() function in the dyna.js file.  We added the scroll options as shown below.

   // Create draggable regions
   for(var i = 0;i < regions_on_page.length;i++) {
      var region = regions_on_page[i];
      // Added custom handle and added page scroll options. (dvw)
      Sortable.create(region, {dropOnEmpty:true,handle:"snl-handle",tag:"div",
containment:regions_on_page,constraint:false,hoverclass:"dnd-droppable",scroll:window,scrollSpeed:50});
   }

> Suppose you have a "drop zone" for dragable items somewhere near the top of your page.
> If you got a longer list of dragable item, you scoll down the page, so that the "drop zone" moves out of the view port.
> Now try to drag an item with the mouse pointer movement to the "drop zone", which sits outside the view port (on the top).
> It's not possible to do this in Firefox 2.0.0.5 on Fedora Core 7. It works fine with Opera 9.2.3.
> As a work around  you can use the cursor key in Firedox to scroll up the page, while you're still dragging the item.
