There is a Mozilla ActiveX Control at http://www.iol.ie/~locka/mozilla/control.htm
This allows, theoretically, for the Gecko engine to be embedded in applications, that rely on IE. A patcher is also available, and sometimes it works.
As it seems, however, RSS Bandit is not patchable this way (I guess due to the use of .NET).
It would be very nice, however, if we could have the Firefox (Gecko) engine as embedded browser, simply, because it offers some more advanced features, that could be utilized (like a better zooming of text, etc.)
Any way for this ?
