How to default to dbo?

I am just trying out SQuirreL SQL for the first time, and noticed that 
it behaves differently than some other database management tools I am 
accustomed to.

I am logging in to a MS SQL Server database, using the jTDS driver, as 
user "hloeblich".  At the top level, I see the list of catalogs(i think 
this is the word), and I can choose one.  After choosing a catalog, it 
looks like I am seeing a list of all usernames.  The problem is that 
there is nothing under any of the usernames except for dbo.  It seems 
that other tools I have used would default to dbo, and not show the 
other folders(if i remember correctly, this whole heirarchy level is 
omitted, directly under catalog shows the tables, views, etc. 
directories).  Is there some way I can make SQuirreL behave this way.  
Please forgive me cause I don't completely understand the user 
permissioning, etc.  I did not set up this database, I just have limited 
access under my username/login.

Thank You,
Hans
