Roberts RD-41 Radio - The 18:10 Crash!

Every day whilst listening to the Six O'clock News from BBC Radio 4; the radio crashes and turns off. This seems to be due to the regular EPG update which arrives daily at around this time.

I've just contacted Roberts Radio customer services. The firmware is: v1.0.0.39.

UPDATE: This has not now happened for many months; so maybe it was a problem with the BBC all along?
