Speech messages that let the player keep moving

Hey there.
I have a scene where the player is being pursued, and while the player runs away, (s)he hears some NPC's talking. However, everytime a message window pops up, the player stops moving, and the pursuer gains terrain. Is there any way of showing the message without stoping the player (as the map name popup)? By the way, I'm using Carmaniac's Bubble Speech. Thank you.
