Right Click Filter not working

[BDEGhost]

I have inherited a database that was created by another employee who has
since left the company. This database contains 4,500 records. We used to be
able to first, display the records in form view, showing all 4,500 records
one record at a time and then be able to Right Click on a field in the form
(for instance, CITY) and from the context pop up menu, fill in the name of a
city you wanted to filter on and then just the records that matched the City
entered in the Filter field would be displayed.
The problem now is that when you right click on a field, nothing pops up, so
there is no way to enter a filter value.
Can anyone tell me what is wrong? This is an Access 2003 database.

Do you know if someone has changed any of the security settings? I'm using
Access 2007 so I don't know where to find it in 2003 (and I'm pretty novice
as well). But in the 2007 security settings, there is an option to turn
on/off access to the shortcut menu. You might be able to use the Help
function to find the access to the security settings in 2003 and have a look.
