Possible Internet Explorer 6+ Dialog Bug

Hello,

When opening a dialog before starting an ajax request, then closing the dialog after completing the ajax request, the dialog visually closes but seems to leave behind a hidden 'screen' that diverts mouse clicks away from simple HTML element below such as a tags and check-boxes.

Example code:

// Open dialog
$('#wait_dialog').dialog('open');

$.post("/ajax/set_user_system_settings.php", function(data) {
// Perform actions on returned data...
// ...
// ...

// Close dialog
$('#wait_dialog').dialog('open');
});

It seems that if the ajax call finishes quickly, the dialog doesn't close properly in IE (clicking a-tags or checkboxes does not work anymore).

Adding a delay to the ajax-called page in PHP using usleep(600000) (for example) remedies this problem.

This happens to me in IE6 and IE7.

Thank you,

Seb
