The Crossfire client has a longer version history, and I want to list bugs I found, using these older versions below the current versions 1.71.0 and 1.72.0

The client does not accept the 'q' key pressed in the command-line, when asked to play again.
The 'a' key to play again works.
Solution : Menu > Client > Disconnect
Affected Versions : 1.11.0 and below.

The client does not connect to localhost:XXXXX entries in the so-called “Metaserver” GUI that shows up, when the client is launched.
The GTK-1 client works fine.
Solution : Use newer clients.
Affected Versions : 1.10.0 and below.

The cfclient says in the -help message, that he would accept the -pix option.
But instead when launched with this parameter, it claims, that this option would be wrong and exits.
In fact, it only uses the PNG picture format.
The client compiles, but a #ifndef will cause the client to exit if no LIBPNG available at compiling time.
Solution : Don't use these -pix, -xpm and -png options.
Affected versions : At least 1.9.1 and later, probably earlier versions.
