Description Michael Catanzaro 2013-07-27 15:21:32 UTC 
Some supported CECP engines don't properly implement CECP undo/remove commands, including:

* Boo's Chess
* Fairy-Max
* Amundsen

This leads to an AI hang when these commands are used.  engines.conf needs a way of indicating that an engine doesn't support undo.  Then either undo should be prohibited when playing against these engines, or we will need to implement a workaround (e.g. tell the engine to start a new game, then replay all moves from the beginning).
Comment 1 Michael Catanzaro 2013-07-27 23:10:46 UTC 
Actually the problem is that we're not putting the engines into force mode before using Undo.  It seems engines react differently to Undo if they're not in force mode.

This problem has been fixed in the development version. The fix will be available in the next major software release. Thank you for your bug report.
