drag/drop buggy in IE

drag/drop buggy in IE


Hi all,
I've been working with the jQuery UI drag and drop for a few weeks,
and got it working perfectly in Firefox and Safari. My problem is
that in IE (I've only tested it in 7 so far), it's not working
properly.
My first problem is that my helper doesn't show up at all. If I put
original, it will throw an error, but if I put clone, it doesn't show
the clone. The drag works, I just can't see anything.
After dragging and dropping, I'm using ajax to reload the page, which
basically resets everything. The only problem is that I can't even
drag anymore after that. It throws two errors:
'tagName' is null or not an object
and
'helperSize.width' is null or not an object
I'm using ajax to load the page the first time, and to reload it after
I drag and drop. I have two different draggables, each with different
droppables, which overlap. Basically, I've created a crude file
system. The files can be moved around the folders by dragging them to
the one you want and also be trashed by dropping them in the trash.
The folders can be trashed only. I don't think that this has anything
to do with my problem, but it might help.
Really the thing that confuses me is why IE7 would be this bad, and it
works perfectly in FF and Safari. There are no errors thrown at all
in the other two browsers...
Thanks in advance for your help,
Sheffield
