jquery autocomplete dropdown doesn't disappear in IE

Question

Hi all,

I have strange problem with jquery autocomplete plugin. Everything works fine, ajax fetching, showing of data, selecting value... But in IE(in firefox everything is fine), when dropdown is opened, if I don't scroll with mouse scroller, but instead if I click on scrollbar and drag it up and down after that dropdown stays hanging on the page and I can't make disappear only if I reload the page.
