jQuery UI Mouse (Slider and Drag&Drop) Bug in IE9

Quick tip: if you are using jQuery UI with IE9, you might hit an issue today. There is in fact a code bug (of the series “do feature, not browser detection”) in the jQuery.UI.Mouse module, which is used by the Slider control or by other drag&drop features.

The jQuery team already identified the issue and a workaround – they are currently working to fix this in the main branch.
