Amundsen Problem

61 reg SE Estate, 6,400 miles.

Today, when I started the car, the display on my Amundsen came up with what looked like a blue MS DOS screen, with lots of small text right to the bottom of the display. After a few seconds it changed to the correct radio display and worked fine. Is this a common fault? Is it the start of a meltdown?

Another annoying habit my car has developed is frequently loosing the one shot electric window function, taking with it the ability to fold the door mirrors from the key fob. I have been able to reset the function by resetting the driver's window (hold switch down at bottom of travel, hold switch up at top of travel) but it is annoying to keep having to do this. Is my car's brain beginning to degenerate?
