Refresh in Relate field Contact

[prajeesh]

Hi

I have a 'Account' Relate field as well as a 'Contact' Relate field which i had added in my opportunities screen. I have added a filter to the 'Contact' relate field so that it fetches the data based on the account I select.
But I have the following problem here:-

If I type 'C' in the Contact Relate field I will be able to see the 'Searching..' message and It fetches all the contacts starting with 'C' but which are associated with the selected Account. But If I change the account,Clear 'Contact' Relate field and type 'C' again, the same Contact list is generated even if I have changed the Account. I believe that it is a refresh problem I mean it is not pulling the fresh data from the server for the same input. How can I fix this. Please guide me.

Thanks,
Prajeesh.
