From: "alan buckley" <alan_baa@hotmail.com> Subject: Patch for RISC OS cursor palette handling in SDL Date: Mon, 07 Nov 2005 09:14:15 -0800 The mouse cursor palette was not correctly restored on RISC OS if the system was using anything but the default mouse colours. Additionally I've modifed the order the wait for vsync is called as it should be after the screen bank switching.
