Empty Column ??

I am having some weird issues that I cannot figure out.
- When I right click on a table using Enterprise Manager and return all
rows I see data except that one column is showing nothing. From in
that window I do a IS NULL query verify that there is in fact data in
the column and a LENGTH to verify it's length.
- If I open up the exact same database from within EM and do a select
ont he table it returns all rows and the column is no longer empty but
is showing the correct values.
I am using SA login for both tools. The column datatyype is VARCHAR
(4000), The tools are local and connection to a DB on another server.
There is no padding whatsoever.
Please help me
Ok I did a RTRIM ont he column and now everything is fine, seems there
were some trailing spaces. WHat was weird though was that in my friend
EM he could see the column fine even when I couldn't. Any setting that
would cause this?
