I'm experiencing a problem that was mentioned on another group: http://www.nabble.com/Dialog-box-not-honouring-height-when-re-opened-td21258793s27240.html#a21390182 "Using the latest jQuery UI (1.6rc4) I am having a problem getting a dialog box to maintain its size when it is closed and reopened. The first, third, fifth... openings render the dialog box at the specified height, but the second, fourth, sixth... opening reduce the height of the dialog box."
