Bug in GNU Chess 4.10 for Windows

[Buzz Bloom]

Hi:

The HELP window for the version of GNU Chess 4.10 for Windows I am using says that the version was ported from GNU Chess 4.0 patch level 77, and it was compiled with Borland C++.

Several bug behaviors occur using the feature Edit->Review Game.  The first bad behavior I  noticed involved an en passant capture.  Review Game showed this move without removing the captured pawn.  I subsequently found some other bad behaviors involving castling and king moves.  Below is an edited listing (the unedited listing was created using Game->List) of a game showing these behaviors.  My edits are inclusions of extra lines with text describing the bug behavior at that point in the game review.

I hope this description is is sufficient for you to reproduce the bugs.  I can also email you CHS files of games (as attachments) illustrating the bugs it that would be helpful. 

Please let me know if you have any questions about this bug description.  I would also very much appreciate receiving an acknowledgement that this message was received and understood.

Regards,
Buzz Bloom
