In events.c around line 2125 (fvwm 2.4 source) you will see
cre->value_mask &= !CWStackMode;
cre->value_mask |= (ecre->value_mask & CWStackMode);
cre->above = ecre->above;
cre->detail = ecre->detail;
/* srt (28-Apr-2001): Tk needs a ConfigureNotify event after a raise,
* otherwise it would hang for two seconds */
new_g = Tmp_win->frame_g;
do_send_event = True;
}
} /* while */
} /* if */
Removing the new_g and do_send_event allows TkCVS to behave, but brings
back the Perl/Tk slow dialog problem.
