Binary star systems I asume you are talking about? They work fine in Celestia. Could you post the code you are using?
Bad ssc/stc code mostly leads to Celestia ignoring the system, so there might be another problem entirely.

also please include the missing NEEDED information

as it stands there is NO / Zero / Nada way to help

"binary" as in what ? star ? or a recompile of the binary program ?
What version od celestia ??
What Operating system ?
What hardware ?
is this a desktop ?
or a laptop ?
or a handheld tablet ?

is there a 3d card ?
or a "chip" on the MOBO ?

and so on ............
