I cannot reproduce this issue shown in the video. What version of UI are you using? Make sure you use the latest 1.5b.

[netdog]

I use lastest jQuery and lastest ui 1.5b.

As I understand this bag appears when one of reverted objects is destructed when there is a holded object on cursor.

set revert:3000 for slower movement of revertment objects. it will help to catch the bag.

If you cannot again reproduce this bug, I can record new video. :)

I think error in helper destructor. I have tried to use $(this).remove(); instead of "self.helper.remove();" and it fix the bug IMHO :)

$(ui.helper).animate(
				{ 	left: self.originalPosition.left, 		top: self.originalPosition.top } , parseInt(ui.options.revert, 10) || 500,
						function() 		{
							if(ui.options.helper != 'original') {								
								$(this).remove();
								//self.helper.remove();
								//self.clear();

								//console.log('remove');
								//console.log(this);
							}

						}

Richard, could you take a look at this? Maybe I'm overseeing something obvious..
