+Mouse Input On Windows
+  ioq3 uses SDL to abstract away as much as possible from platform specific

+  and limitations with respect to mouse input on the Windows platform. We
+  provide a patch against the SDL subversion 1.2 branch which fixes the
+  following problems:
+
+    * DirectX (and thus DirectInput) driver not functional when using an
+      OpenGL SDL_Surface.
+
+    * DirectX (and thus DirectInput) driver not functional in windowed mode.
+
+    * Mouse buttons 4-7 unusable with the DirectX driver due to DirectInput 5
+      not exposing the required functionality. Use DirectInput 7 instead.
+
+    * Low quality mouse input data when using the windib driver due to use of
+      WM_MOUSEMOVE events. Use GetCursorPos API call instead.
+
+  The patch can be found in misc/sdl-win32-mouse-fixes.diff.
