Cannot see dm_db_index_physical_stats

Hi

I have a number of DB's set up on a SQL 2008 instance using 2005 compatability.

I would like to see the level of fragmentaion on the indexes however when I right click on index, slect properties then fragmentation, I'm getting a blank window.  I've checked under views \ system views and sys.dm_db_index_physical_stats is not showing on either the DB I am trying to review or the master DB.

I can however run DBCC SHOWCINTIG (table_name, Index_name) and get an output. 

Any ideas as to what may be the issue?
