IE8 crashes after drag and drop

I am trying to drag and drop in the exemple 20_tooltip.html on IE8 8.0.6001.18702 on windows XPSP2 and after three or four moves the browser crashes.

Anybody have ever seen this happening?

I have got this error after the crash. I put my printscreen for more details.

Unfortunately we can’t reconstruct it locally.
Please try to run IE in “without extensions” mode and go through the same steps.
( it hardly possible that js code itself can crash browser, most probably it is side effect of some IE’s extension )
