Sortables - IE 7 revert - zIndex - Varying Size Sortable Items


I downloaded the latest UI build 1.5b2 running on JQuery 1.2.4a.
Target browser is IE 7.
I am creating a portal where users can drag and drop portlets from one
zone (sortable) to another. I have found 3 bugs so far.
1) IE 7 Revert - When I enable revert, if I drag sortable items
really fast over and over, they often overlap each other and get
bugged out.
2) zIndex - When using multiple sortables with connectWith, if I drag
an item from Sortable A to Sortable B, the item's zIndex is messed up
when hovering over Sortable B items. It lies beneath items in
Sortable B. Now if I drag items from Sortable B to Sortable A, it
works fine. I've messed with the zIndex properties on both to no
avail.
3) Varying Sized Sortable Items - If I have a tall item in Sortable A
and want to drag it to Sortable B or even keep it in Sortable A, the
calculations for intersection are invalid. I am unable to drag the
larger item around unless I have a very large area to work with. I
often find myself needing to go outside of the bounds of the browser
to get it to work.
