I had a similar problem to Becky's, but it was the first time it's happened, and it was with the 0.5W version, which I've used since it's release with no problems.
While racing online, I crashed and went to spectate mode. I got the chrome screen, but the race continuted, and I could see people typing comments.
I went to the garage, and everything was normal. I went back to spectate, and got the same chrome screen.
I went back to the garage, then used the 'pit' button. I was sitting in the garage and could see the track outside, but anytime I used the tab key to view other cars, I got the chrome screen ,and could not get rid of it until I used 'garage' and 'pit' tabs again.
Going from garage to spectate - always the chrome screen
Going from garage to pit - everything fine until I tried to view another car
This continued for 10 minutes, at which point I quit the game.
I'd seen the chorme screen occasionally flash on for a few seconds when waiting for a race to start, for example, but never before has it continued
like this.
