Thanks, Danny, even if it isn't what I wanted to hear.
And, yes, you're right, it was related to the Phidget which I have that I came across that reference and it gave me a bit of false hope :-(((
I just may have to capitulate to an iPad to use for this one application.
It's either that or Artisan, but Artisan doesn't "do" inventory (at least I don't think so).
In any case, thanks for the reply.
