No, just a different VOX algorithm, it's in the documentation. >As you will see in the data summary below, there are still quite a few >responses in the azk file.

But it makes no sense having the VOX  present thousands of responses so I'll look at it. >In addition to the findings I just listed, I also found a problem in the >output file regarding the keyboard response--even though I have  in >item 2, when I pressed "J", the RT always showed up positive. > >       >     > >+1      "sentence1"  start> /  "sequence 1"/*!; >+2      "sentence1"  start> /  "sequence 1"/*!; > >Could you let me know what the problem might be?    Zil will only look at the first response and that's the +DigitalVOX  which is correct.                                                 /"\\   -jonathan (j.c.f.)                            \\ /                                                  X      ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL  / \\    DISCRIMINATE, v.i.
