Refreshing Icons after modifying File Associations

Is it possible to force the refreshing of the icons associated with files after having modified them using the file type setttings of Opus.
right now i need to exit (kill) dopus and re run it to see the changes.

Thanks

Opus caches the icons to speed things up. I don't think there's currently a way to tell it to rebuild the cache but you could ask GPSoft to add a command or make it happen automatically when you change the icons, at least if it's done within Opus.
