I'm curious how you are using the mouse on Solaris then...

configure --prefix=/tmp/FOO --without-gpm-mouse --with-screen=ncurses

It's fairly obvious if you run MC in an xterm using the ncurses 
configuration.  Rather than interpret the mouse, it simply echos the
printable characters from the escape sequence in the command-line window.

I didn't bookmark it (and scanning back through google for the past 5 days 
doesn't show me).  There's some discussion on gentoo regarding 
line-drawing characters, and

http://bugs.gentoo.org/show_bug.cgi?id=146570

mentions a problem with function-keys.  But the remark that I had in mind 
was to the effect that the interpretation of the escape sequences had 
changed from one release to another (that sounds like a comment on one of 
the Debian lists).
