tin modifies terminal settings

Hi,

experimenting with tin I just found out that it somehow messes up
terminal settings.

  'uname -rms' -> Linux 2.6.33.1-spott i686

  $ ncursesw5-config --version -> 5.7.20081102
  $ ncursesw5-config --abi-version -> 5

  $ tin -V
  Version: tin 1.9.6 release 20100313 ("Lochruan") Mar 29 2010 22:46:39
  Platform:
          OS-Name  = "linux-gnu"
  Compiler:
          CC       = "gcc"
          CFLAGS   = "-g -O"
          CPP      = "gcc -E"
          CPPFLAGS = "-D_GNU_SOURCE"
  Linker and Libraries:
          LD       = "gcc"
          LDFLAGS  = "-g"
          LIBS     = "-lcurses   -lidn -licuuc"
          PCRE     = "8.02 2010-03-19"

          -REQUIRE_BRACKETS_IN_DOMAIN_LITERAL -FOLLOW_USEFOR_DRAFT

The terminal itself is /dev/pts/3, handled by tmux inside rxvt-unicode,
most recent versions.

When I use "rtin", all the color settings affect only where "tin" writes
text, everything else is left at the current default colors.  I always
thought this to be tin specific, but I am not so sure anymore, because
after exiting "rtin", the same behaviour persists in "bash" as well!
I didn't notice until now, because tin runs always in its own
tmux/screen managed window which closes after "rtin" exits.

I have tried a number of times to set tin's colors to "DEFAULT" both for
fore- and background, but this doesn't work, so I settled with ANSI
colors, white text on black background.  Now these colors are set in
bash as well:  text is white on black and where there's no text, I see
rxvt-unicode's default colors (light sand on saddle brown which puts the
least strain on my eyes).  This grows into a problem when white-on-black
spots are littered about the screen.  BTW, "tin" is the only curses
application behaving this way!  I regularly use "elinks", "mutt" and
"vim": no problem there.

Does "tin" do something out of the regular curses way when initializing
and de-initializing curses?
