When calling $.dialog(...) with using an Event object as "pos" parameter throws an "Invalid argument" JavaScript error in MSIE (7+). It works when passing an x,y array though.

onChangeMonthYear recives the wrong date when working with a restricted date range.

This only happens when you switch the year(selecting it from the drop-down list) and the selected month is out of the datepickers range (in the year you selected).

onChangeMonthYear recives as paraeters the newly selected year and the selected month (the date isn't in the allowed range). The datepicker displays a different month (the first or last within the alowed range)

A solution (for tabbing only, mouse click is less of a problem):

Add this code:

else if (event.keyCode == 9) {
// tab out while animating in
$.datepicker._hideDatepicker();
handled = false;
}

Here:

_doKeyDown: function(event) {
...
break; // +1 week on ctrl or command +down
default: handled = false;
}
>>>>>>>>>>>>>>>>>>>>> here <<<<<<<<<<<<<<<<<
else if (event.keyCode == 36 && event.ctrlKey) // display the date picker on ctrl+home
$.datepicker._showDatepicker(this);
else {

And in: _hideDatepicker: function(input) {

Comment out:

if (this._datepickerShowing) {

and the closing }
