I've tried from both a console window and mintty and experience the
same behaviour.

This only occurs for any file in /etc.  For simplicity, I tried:

$ cd /etc
$ echo "Some text" > test.txt
$ cat test.txt
Some text
$ vim text.txt

and all I get is a screen with nothing but "test.txt" in the lower
left hand corner.

Ah, so the permissions on tty0 look correct:

$ ls -l /dev/tty0
crw-rw-rw- 1 csutclif Users 136, 0 Nov 30  2006 /dev/tty0

How do I capture the strace output to a file?  I tried 'strace vim
/etc/passwd > strace.out' but vim complained about stdout being
redirected.

Thanx!
