Im trying to call FXApp::flush() from one of my methods wich is called when a button is pressed. I get an "Undefined method 'flush' for Fox::FXApp" error. When I print all public_instance_methods for FXApp, I can see flush listed, so I don't really understand why it doesn't work. I spent the last day with reading all the documentations regarding inheritance but I'm unable to figure out how to call it correctly... :o(( (Lyle thank you for your suggestion regarding the Changing Button Icon problem.) Best Regards, Steve
