Dialog won't reopen if hide effect used on close?

It appears that using a hide effect on a dialog causes problems with reopening the dialog after having been closed.

My code:

$(function() {

$("#profiledialog").dialog({

title: "Employee Profile",

width: 608,

modal: true,

resizable: false,

hide: "puff",

autoOpen: false

});

});

function openProfile() {

$("#profiledialog").dialog("open");

}

I call openProfile when I want to display the dialog. When I close the dialog, it closes with the "puff" effect correctly.

However, with the code as shown, when I subsequently call openProfile to open the profile again, the screen dims (as it should with a modal dialog) but the dialog itself does not reappear.

If I remove the "hide: 'puff'" option, when I close the dialog and call openProfile(), the dialog reappears as expected.

Could it be that the "puff" effect leaves the dialog in an invisible state? If so, how would I restore the dialog to its original state following the puff effect?
