:no, that's a p2 400 of somebody on IRC.

    Well, fix the program first.  When you print out the
    raw data iterate from total to total + readcnt, not
    from 0 to total + readcnt.

    The if (total >= sizetab[level]) ... needs to be
    while (total >= sizetab[level]), otherwise if enough
    mouse movements build up you will overflow your buffer.

    It should still have worked reasonably well, but 
    perhaps fixing those two issues will make the problem
    more obvious.
