XTerm & OpenSSH question w/ freezing.

[war]

Sometimes when I use openssh (latest) and do find . or ls -lR /dev or
similiar, my xterm 'freezes up', there is no way to fix it but to kill the
xterm usually.

This NEVER occurs in telnet.
The error is completely reproducable when you come across it.
ie: one may just be browsing the filesystem and when you come across this
problem, you can launch another xterm and the EXACT same thing happens
when you try to do it again

Bug reports on similiar issues seem to be sparse and people I know never
seem to have the problem, perhaps they use ssh from a windows machine.

I was wondering what causes this, and is there a way to fix it?
