Hi Ken,

Well I managed to install Tk using PPM as you suggested, so that went well. The code worked first time, so that was good to see.

I'm off to the states next month (I live in Brazil), so I thought I'd try to buy a cheap touch screen monitor while I was there. I get back in Jan, so I'll try and play around with this code more when I get the screen and I'll post some snippets.

Thanks for the taster.

Regards

Steve
