DatePicker uses the alias '$' in within the control which doesn't respect the environment. For example, if the alias '$j' is used on the page for jQuery integration with other libraries datepicker breaks on certain events such as onmouseover which dynamically adds a class.

To Test, simply use the noConflict call on jQUery and assign $j to that. Then try to use the date picker.

If the drag handle of a draggable element is outside of the element's bounds (e.g. it is absolutely positioned to be above the element) and no cursorAt is set (so cursorAtIgnore is true), slowMode winds up getting set to false when it needs to be true.

I have attached a patch in which I simply added a check for whether cursorAtIgnore is true, in which case slowMode must be true.

Look at the second line of the code: WIDTH !!! should be HEIGHT. It makes Drag&Drop module not working (tolerance):

function outerHeight(el) {

var $el = $(el), oh = $el.width(); for (var i = 0, props = ['borderTopWidth', 'paddingTop', 'paddingBottom', 'borderBottomWidth']; i < props.length; i++)

oh += num($el, props[i]);

return oh;

}
