Woo! First error message!
Okay, running the game,even without changing any settings, brings the following error:
"Failed setting buffering: DI_POLLEDDEVICE"
From there, I cant move to any menu items, the app seems to accept no keyboard input. Normal windows command work (ctrl-alt-del, windows key)
Wait a sec, just figured it out. I had by Xbox controller plugged in. A soon as i took it out and re-fired SW, it worked perfectly.
Anyway, its still a bit of a bug report, as I hadn't selected to
use the joystick, only mouse and keyboard. Meh.
Huge round of applause to you Jonof! Now we can finally play SW in all its glory!
