Hello,
I cannot solve all problems with one small fix. The location, which I fixed
did overwrite an unsaved game without warning. This is what I prevented and
there is no alternative. There may be other locations doing the same. It may
be worth to check every place where the game is changed (to the first of the
filter) without warning. If any feature has a problem with my small fix, its
implementation has to be fixed because then its built on wrong assumptions.

Hi,
I suggest we analyze this issue a bit further...

Gerd, your suggestion does not resolve the problem above.
After tree completion I am still sent back at game#1 of dBase.
But there /is/ a change:
When I exit Scid at this point, Scid produces an "unsaved game warning"
and it appears that my new game is not entirely lost (as it was), but
added as a new game to the tree base.
Hm...
Cheers,
Joost.
