I know a determinant function is included in the matrix routines. Would that be the only test to check?

ODD!
Looking at the algorithms it would seem that KMO would be undefined (don't we need R inverse for AntiImage matrix) and Bartlett 0.000 in the presence of a 0 determinant.  Mind doing a MATRIX out on the factor and attaching the correlation matrix/means/SDs (MATRIX SYSTEM FILE).
