Sql developer hanging while quering table with clob [message #481022]

I have some tables which have LOB columns.

For eg: Transmission.

When i query
select * from Transmission where rownum < 2. it hangs

Even thought it retrieves 1 record, its hanging because of CLOB column. I tried find settings but couldnt.

Did any face similar problem? Where i can do any settings? is there a facility to set CLOB limit ?

Thanks in advance
Sam
