I'm getting the following error from my program, which continues to run,
but doesn't perform as expected..

ERROR #1  gl_invert4d :  ERR_SINGMATRIX


My first throught is that somehow I'm passing in a non-invertible matrix,
but that seems rather difficult, since the only time I use loadmatrrix()
is with a predefined 4x4 identity matrix.  

Any details on exactly what this error is and possible causes/fixes are
appreciated.  Replys though here or email are fine...
