If I attempt to do the sequence of events as follows:

<pen down/move>
GrfAddPoints (repeatedly)

<pen up>
GrfFilterPoints()
GrfMatch (NULL, data, &dl, &urc, NULL);
GrfFlushPoints

If I look at data, it usually works ok, with some exceptions.

One execption is that when I write an 'a', it will correctly match
it, but then on the subsequent recognition (let's say I write a b),
it will now recognize "ab" ... this eventually stops but it's obviously
annoying.

A solution seems to be to put a GrfInitState right after the FlushPoints,
but that seems to slow things down. What am I doing wrong in this
sequence?
