Hi there,

I am attempting to read Graffiti from the normal screen area (above the
graffiti area)

Most of the time it works fine - however, every now and then it goes beserk
recognising wildly different characters than what I have written even though
the onscreen representation is pretty much the same as before. (I am only
trying to recognise digits by the way)

I am using the following API calls (in this order)

GrfFlushPoints()     // To flush any previous points
GrfAddPoint()         // In a loop to add my previously drawn points to
graffiti's buffer
GrfSetState()         // to place the recogniser into numeric mode (ie only
recognise digits)
GrfFilterPoints()    // to thin out the buffer
GrfMatch()                // to match the digit drawn

Is these the correct functions to call, in that order? As it works about 85%
of the time, I assume I'm on the right track, but its the occasional wild
failures that make me think I have missed out something else.

I'm happy to provide all the code if required, but at this stage its a
general enquiry as to the correct way to go about reading graffiti from the
screen.
