Do you get the Dialog Box "Drag & Drop failed"
I have found there is the strong possiblity of a crash very soon after this.
Sorry have no answer for you but would also love to know why this occurs and why it has not been fixed, as, in my experience, this issue/bug has been around for many versions.
I would suggest a look thru current SPR's if you can figure out how to get into that particular part of website.
Deepak Gupta seems to have a handle on searching this area and coming up with an answer.
