I thought recording was now the only cause of lock-ups but have just had one without recorder running. I got the grey line across the screen and the map then went all grey. I had to Ctrl/Alt/Del to exit and when I rebooted I still got the grey screen which appeared to have been saved by RB as the new default screen. Note I had not asked for the grey screen to be saved, it just happened. I had to completely shut down my PC and on reboot got the world map, I tried using default but as stated that was now a grey screen. Have replaced the damaged default with my requirements again.
It would appear that occasional crashes are still occurring :-(
Just one thought - at the time my coverage had ben greatly reduced by a heavy snow storm, and traffic pick up fell to a very low level.
