I am using dialog plugin from jQuery UI 1.8.17. The following code works and opens the dialog properly. But setting any option on dialog dosen’t work and makes the dialog transparent.
This happens only in IE9
jQuery('#faxdirectory_dialog').dialog().dialog("open");
jQuery('#faxdirectory_dialog').dialog("option", "height", 500); // this doesn't work.
We were using jQuery 1.4.2; we recently upgraded to 1.7.1 that seems to have fixed it. But the problem most certainly was not that, we have whole bunch of other jQuery plugins and the way they work with each other might be an issue.
Will update the answer when I can pin point exact issue.
