Using 3.7.2 (IE6),

I click on the search button to bring up the multiple search dialog, then select a date type column which I have attached a datepicker to, using searchoptions.dataInit property (as found in the wiki).

What happens is, I click on the data input field to pop up the datepicker but I close the search dialog instead of making a date selection.

The search dialog closes but the datepicker remains.

On a side note, in FireFox, the datepicker is popping up under the search dialog.
