[Chessx-users] Mysterious unreproducible "Find Position" behavior

[Fex X. <fs...@gm...>]

I was getting some very mysterious "Find Position" behavior that I was not
able to reproduce.

I had a file of 11 positions in pgn format. I made one move in the game 1
position, then did "Find Position".

chessx was supposed to find game 8 in the file.

But it didn't , it just indicated "game 1" in the games list.

I tried for about 45 minutes to get a minimal example of this behavior,
carefully copying games one at a time from the original file to a new file.
The program would always seem to work in the new file until the new file
had all the games in the original file.

Finally, the program *worked* again in the original file: it found game 8.

I haven't even the slightest idea of what is going on. Some kind of caching
behavior maybe? Has anyone run into this or can give insight into what it
might be? Like I said, I cannot reproduce the issue for now.
