Date: Thu, 05 Jun 2003 09:36:40 +0100 From: "alan buckley" <alan_baa@hotmail.com> Subject: Modification for RISC OS SDL port My name is Alan Buckley and I have been working on the RISC OS SDL port. I've attached a modification to SDL_WimpVideo.c to this email that ensures the Window is displayed immediately when the video mode is set to a windowed mode.
