Manifest or Theme/Style for a IWebBrowser2 control?

The IWebBrowser2 control has password edit boxes which are squares. This happened many years ago if you were on an XP machine, and you had a password edit field without a manifest file, you would get squares (no character found for the * they put in there with that font). My application has a manifest file. However I don't know how to give a manifest or set the theme开发者_开发技巧 or style of the control that is created. Any ideas?

Thanks!

Specify DOCHOSTUIFLAG_THEME in your implementation of IDocHostUIHandler.
