By the way, I don't understand why using sudo is dangerous (really, I'm a Linux dummy )
It runs openoffice as administrator. This is a big deal.
User accounts don't just organize your files, they exist to protect each other from unauthorized or accidental access. They can only access files they own or are allowed to access. Now, administrator can access anything on demand, up to and including your hard drive's boot sector, just by writing to the wrong files! Running any program as root means that, if you make a mistake, the consequences could be dire:
It's not just humans that make mistakes either, buggy programs crash too, especially big complicated ones. If you don't need to trust something with root, you just don't. Running openoffice as root isn't something I'd reccomend at all.

tty
TTY(4) Linux Programmer's Manual TTY(4)NAME
tty - controlling terminal
DESCRIPTION
The file /dev/tty is a character file with major number 5 and minor number 0, usually of mode 0666 and owner.group root.tty. It is a syn-
onym for the controlling terminal of a process, if any.
In addition to the ioctl(2) requests supported by the device that tty refers to, the ioctl(2) request TIOCNOTTY is supported.
TIOCNOTTY
Detach the calling process from its controlling terminal.
If the process is the session leader, then SIGHUP and SIGCONT signals are sent to the foreground process group and all processes in the
current session lose their controlling tty.
This ioctl(2) call only works on file descriptors connected to /dev/tty. It is used by daemon processes when they are invoked by a user at
a terminal. The process attempts to open /dev/tty. If the open succeeds, it detaches itself from the terminal by using TIOCNOTTY, while
if the open fails, it is obviously not attached to a terminal and does not need to detach itself.
