Dialog wont open on second click (1.6RC). Help!


Hi all,
I downloaded the latest 1.6RC from jqueryui.com and found that the
dialog window does not work as well as in the currently available
stable version(1.5.3). I am not a javascript expert...what i am trying
to do is open a dialog window on the click of a button. It opens fine
the first time...on closing it and clicking on the button again, it
refuses to open on 1.6RC version of the code....but works fine on
1.5.3.
Here is the JS code I am triggering when a button is clicked.
<input type=button value="click" onclick="javascript:openOver()"/>
function openOver()
    {
            $("#dialog").show().dialog({
            bgiframe: true,
            height: 300,
            modal: true,
            buttons: {
                'Submit': function() {
                    $(this).dialog('close');
                },
                Cancel: function() {
                    $(this).dialog('close');
                }
            }
        });
    }
<div id="dialog" title="Create new user" style="display:none">
    

All form fields are required.


    <form>
    <fieldset>
        <label for="name">Name</label>
        <input type="text" name="name" id="name" class="text" style="width:
230px"/>
        <label for="email">Email</label>
        <input type="text" name="email" id="email" value="" class="text"
style="width:230px"/>
        <label for="password">Password</label>
        <input type="password" name="password" id="password" value=""
class="text" style="width:230px"/>
        <label for="password">Date</label>
        <input type="text" id="datepicker">
    </fieldset>
    </form>
</div>
