Decrypting file encrypted for multiple recipients using a given ID?

Dear all,

I have a file encrypted to two different User ID's, both for which I
have the public keys as well as the secret key. When I try to decrypt
the file, it always prompts me for the passphrase of user A, while I'd
like to decrypt it using the passphraseless key of user B.

I've tried various combinations of -u with and without exclamation mark,
but without success. How can I specify that the key of user B should be
used?

Thanks in advance,

Remco
