When I run my Performer application, I sometimes get the message:

"Singular matrix in routine LUDCMP"

There is no mention of LUDCMP in any gl documentation I can find. It
probably just means I've got a matrix of all zeros on the stack or
something, but could someone clear this up for sure. Any pointers on why
this might be happening (sometimes) would also be ace.

Has anyone else had this problem?

Thanks,
Rob.
