Bouncing and panning?

when ever i bounce a track, my panning get all consolidated. All vocals or instruments i want in the left or right ear only, gets centered wen i bounce the track! is there a reason for that? or am i not doing something right?

Are you bouncing your mix to mono file by an chance? I would check your bounce setting's to make sure its set to a stereo file.

lol problem solved! thanx alot
