GnuBG help

I just downloaded and started using GnuBG (Windows) and I can't figure out how to get the computer to make a move. It made the first move, then I made a move. Now how do I end my turn? The manual just says click the dice. Well I've clicked just about everywhere on the screen including the dice and the "Go to Next Roll" button and nothing is happening. Any help for a newb would be much appreciated. Thanks.

Hmm. Clicking the dice always worked for me. But I got XG 8 or 9 years ago and haven't used GNU since.
