But it is sufficient when *only the King* has moved before, to loose the
castling rights. That's not too unusual IMO. I notice it myself then and when in
blitz games, when I want to castle but can't :-) because I forgot that there was
something like Ke8xf7, and later Kf7-e8...

WinBoard 4.2.6 shows the same behaviour on my computer:
3qk3/8/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQ e3 0 1

I've noticed that it adds the castling right even immediatly after pasting the
position into it:

3qk3/8/8/8/8/8/PPPPPPPP/RNBQKBNR w KQ - 0 1

This may be related to a "simplification" of the edit position mode... I don't
see an option there to set the castling rights.

That can affect test position results determined with WinBoard!
