Short – In the next alfa release (comming soon) I do not support (and will not support) jQuery UI Dialog. Using UI Dilaog causes a lot of problems and moreover it is so slow in IE. Finaly I make a decision to implement my own modal function which can be seen in the upcomming release. It is not finished yet, but I hope that it will be done until the finall.
If you switch to jqModal you will not have such problem.
