"This page has an unspecified potential security risk" message in IE

I am integrating the excellent Picnik into our app and would like to host it in an iframe within a showModalDialog().  This works fine on all browsers except IE, which pops up several boxes saying "This page has an unspecified potential security risk" which are clearly an irritant and scary for the user.  Doing some Googling, this seems to be related to a Flash app trying to run certain bits of JavaScript in a modal dialog.  Has anyone got a workaround for this other than not using a showModalDialog?

It looks like the potential security risk with macromedia eLicensing client activation, and this potential vulnerability does not affect products installed on machines... it could be risky.
