Very interesting. I experienced the same problem, none of the directional arrows would work on default view,started with an IL2 after the update. The fix for me was simple, and I have no idea how it worked or why..but all I did was redownload and install the hires texture pack. Still happens occasionally, so i keep a copy of hires pack on desktop and redeploy it when it happens,reboot and bingo it's good. b49
