Windows XP at the moment - though I will try and get it upgraded to Windows 7, especially if that might make a difference Best wishes Caroline

My code works fine with a standard mouse but I'm getting strange errors when I try with a touchscreen monitor - I would be grateful for any advice at all. The problem is that the mouse position co-ordinates I get from the touchscreen don't bear any relation to what I get with a standard mouse. Its a USB HID touchscreen so I had expected it to act like a mouse with one button. But, for example, the following section of code prints appropriate mouse co-ordinates if I click the 'normal' mouse, but strange (meaningless?) co-ordinates if I touch the touchscreen, even though the mousemotion and mouse button events are identified as the correct type. for event in pygame.event.get(): print pygame.event.event_name(event.type) if event.type==MOUSEBUTTONDOWN: print event.pos My display is set up simply like this: windowSurface = pygame.display.set_mode((0, 0), pygame.RESIZABLE, 32) ... and I'm working in Windows for this project. I've already tried updating my drivers and my version of directX, and have calibrated the touchscreen using the software provided with the laptop - it works fine for other programs. I'm not an expert programmer so would be grateful for any advice - is there something I have missed about setting the display, or about using two input devices? I'm really stuck! Any advice gratefully received - many thanks, Caroline
