--- Comment #484 from Pilot pilota51@gmail.com 2011-05-05 03:24:01 CDT --- There appears to be a regression in 1.3.18 for Raven Shield. In 1.3.17 and earlier, setting MouseWarpOverride to force worked perfectly, but in 1.3.18 and 1.3.19 it doesn't work at all. The cursor is stuck in the middle of the main menu and the mouse escapes. The keyboard cannot be used to navigate the menu, so it's now unplayable.
I also have Unreal Tournament 3 and I haven't noticed any change in this bug for it. In this case MouseWarpOverride force works as before: prevents mouse from escaping, but locks it to center of menus and requires keyboard navigation.
