Description
I launch mc, go into the "Options"/"Configuration" menu, put a marker on the "Verbose operation", then press save ("auto save setup" is marked). When I launch MC next time and go to "Options"/"Configuration" menu — there is no "Verbose operation" marker.
I tried to "rm -rf ~/.mc", there was no result.

Replying to andrew_b:
What about other settings?
Other settings (I tested few) saving and loading normally
I am also tried to turn off autosave, then edited the ~/.mc/ini, but "Verbose operation" wasn't loaded.

Looks like you terminal is slow. On slow terminal, the Verbose option is forced set to 0. This can occurs in 2 cases:
1) you launch mc with -s/--slow option;
2) S-Lang (or NCurses) determines that the output speed (the baud rate) of your terminal is less than 9600 bps.

I launch mc without -s/--slow option;
I use urxvt terminal with speed 4000000 baud (as "stty -a" says);

I've downgraded urxvt now to 9.07 version. The MC works fine in it (saves and loads the subj option well). And stty says that terminal speed is 38400 bps. So maybe it is an urxvt bug.

OK. Closed.

I think I should reopen this bug, cause I talked to urxvt developers and they confirmed the urxvt baudrate is 4000000.
I modified the midnight.c a bit (insert "printf("%i", tty_baudrate ());" before tty_baudrate check) to see what tty_baudrate returns and it returns "0" on the recent urxvt. So this is mc/slang bug (because "stty" returns the correct value (4000000) ).

OK.
404 int 405 tty_baudrate (void) 406 { 407 return SLang_TT_Baud_Rate; 408 }
Since MC gets baud rate directly from S-Lang, I guess, this is bug of S-Lang. Please send a bugreport to S-Lang developer.
Would you build MC with NCurses and show the result here? Thanks!

Reported the problem and the patch for S-Lang to the slang-users-l mailing list:
http://mailman.jedsoft.org/pipermail/slang-users-l/2011/000722.html
Applying this patch to S-Lang fixes the mc+urxvt problem for me.

Cool! Thanks!
Actually, this is not mc bug. Closed.

It's definitely a mc bug, cause you should not turn off the verbose mode automatically on slow terminals, but you should leave it as an option.

+1 for disabling the automatic non-verbose mode
people with slow terminals should be able to add -s to their command line. there is no option to force verbose mode for those with urxvt (and maybe other terminals)
this problem also exists in the ncurses version of mc:

gdb tells me that tty_baudrate () == -1
that is less than 9600 but a invalid value in my opinion, therefore this should not cause mc on modern systems to fallback to minimal functionality.
the issue can be solved with this patch. you have to enable verbose mode when it was disabled with a unpatched version.

I found a solution:
stty 115200
just before starting mc (or somewhere in your scripts)
There is redetermination: it saves settings well, but doesn't load it next start and rewrites in to default next shutdown.
