In case you are wondering why I absolutly have to use standard dialogs: I am displaying the CuteEditor in an IFrame which is causing several problems as descripbed here: http://cutesoft.net/forums/thread/45310.aspx As Adam suggests in that thread, the standard dialogs resolve the problems. This demo page very closely mimics my situation: http://richtextbox.com/test/iframe.aspx and I can reproduce the problem in that demo page as well.

 

I feel like I'm trapped: I have to use the standard dialogs in order to overcome the problems related to displaying the editor in an iframe but standard dialogs cause Flash to be used and the file browse dialog is disallowed in that situation.
