SQL Developer fails to query table

Question

I am trying to use SQL Developer (v3.2.20.09) to query a particular table in an Oracle 10G database using a simple "select * from table" query.  When I run the query SQL Developer sits there forever waiting for results but nothing is every returned.
The table is relatively small, just a few thousand rows and just half a dozen columns (mixture of numbers, short text strings and datetimes).  I can run other queries on the table in question so I know I have privileges, it's just when run a simple query to return all columns and all rows it fails.  I even tried to an export of the table using Tools->Database Export but that too just sat there forever failing to complete.
Any ideas?  It seems that there is just something in the table that SQL Developer doesn't like.

I've never used sqlplus before but I just tried it and it runs the same query (select * from [table] where rownum <= 40) without any problems.  The strange thing is that once I could see which row was row 40 in sqlplus I queried just that one row in SQL Developer (using the primary key column) and it worked fine.
I did a bit more experimenting and it doesn't look like a problem with that row in particular just with displaying more than a certain number of rows.  The first column on the table is called OBJ_ID and is a unique integer which forms the primary key.  Row 40 has OBJ_ID = 53.  I tried running:
select * from [table] where obj_id between 40 and 53 - no problems
select * from [table] where obj_id between 30 and 53 - no problems
select * from [table] where obj_id between 20 and 53 - no problems
select * from [table] where obj_id between 10 and 53 - failure as above (no errors but SQL Developer never displays the results)
