46 Very strange (as someone else said.)
47
48 Only thing I can think of is that something in your startup scripts
49 (.profile, .bashrc, etc.) are doing something different between the
50 two logins.
51
52 I've seen that most often when they do things based on TERM and it's
53 different between a local login and remote.
54
55 Maybe make sure your startup scripts run with a 'set -x' at the
56 beginning and compare the output?
57
58 Good luck,
