OpenPGP card's RNG

Does GnuPG (1.4.6 / WinXP) use the internal random number generator of
the OpenPGP smart card?
In other words: Is it useful to keep the card in the reader when running
GnuPG even when I am not using the card directly (i.e. encrypt only)?

I'm just curious because I noticed the "GET CHALLENGE" command while
reading through the card spec...

Have fun,
