[jQuery] mouse flicker when animation is taking place in IE

[joomlafreak]

I have a very simple question. Whenever fading out, fading in,
slidedown, slideup etc animations occur (for me on my notebook), the
IE shows flickering of mouse over the screen as if it is downloading
something. Thats does not happen in FF. I wonder why does this happen.
Im sure it is not a bug but some default property of our beloved IE
that does it and I hope there is some extra line of code (like !
important in css) to tame this behavior in IE.
