    Test version.
    detects text only when no other detection is in progress.
    contextModel2 is now:
    Code:
     if (filetype ==TEXT) { 
        sparseModel(m,ismatch,order); 
        distanceModel(m); 
        wordModel(m); 
        } 
    	else { 
    	picModel(m); 
        recordModel(m); 
        indirectModel(m); 
        dmcModel(m); 
    	}

    Speed is faster. Compression is worse. Efficiency better.

    Test this version.

    Interesting idea KZo
    Code:
