After using Vue4 Mac for a while, I can assure you that it has much bigger problems than the nudge keys not working. Besides redraw problems where things don't appear in the material editor and such, I've managed to crash it several more times. At one point I had to reinstall the app just to get it to launch properly. I had done a save & quit, which seemed to save but not quit. I pushed the red "x", but apparently it was still doing something because it crashed and left that file messed up - along with everything else. My most recent crash left me without the scene file I was working on (unless I'm just really confused and didn't save this time around, but I thought I had). Fun, :( - n8
