Is it possible to have background animations running while having the player choose between dialog options?

Not directly, no. The game is completely paused while the dialog options are displayed.
There's a link to a workaround in the tracker entry Scummbuddy posted.
Thanks for the input. However, the workaround would cause very much work for this minor problem, so I guess I'll just have to wait for a possible AGS update with this feature.
