I have a drag-n-drop script that works fine in Chrome and FF, but it doesn't work as good in IE. I have a navigation from which blocks with content can be added. These blocks can be arranged with drag-n-drop. When adding two blocks, the first block is stuck in IE and cannot be dragged, unless the whole page is refreshed.
If possible maybe the script can also be cleaned up where necessary.
I've added an attachment to explain better what I mean. If needed, I have a stripped version of the site online to reproduce the bug on-the-fly.
