Fullscreen issue - latest exp builds

-I’ve tested this for the latest 4 experimental builds (and some random further exp builds)
-exp. SDL version (list accesible through main page)
-windows os (i’ll check later if it occurs with the linux build) EDIT: it isn’t an issue for the latest (05cd920) exp linux build (ubuntu 14.04)

When I set the option ‘fullscreen’ to ‘true’ and then restart the game, I can no longer navigate properly in the main menu using the arrow keys nor the shortcuts (more specific: it jumps randomly(?) from ‘new game’ to ‘quit’ to ‘load game’ to ‘world’ to … (you get the idea))

(this doesn’t happen with the latest stable version)
