Seems i have AMD Firepro M400 and the driver seems to be upto date, i'm using windows 8.1.

Not much i can do about it as its company issue. I'll try tomorrow to see if it's ok with an external monitor. The only other alternative would be program something independently, the form coordinates seem fine its only the actual screen coordinates that are wrong.

Well turned out to be screen resolution! It works fine at lower screen resolution but at the highest (Recommended!!) screen resolution it does not work! Somehow, somewhere, the location is being multiplied by some ratio of the supposed screen resolution and what it perhaps thinks is the actual screen resolution. Very weird and raises the possibility that it wont work on everyones computer!!

Yes, i've tried the microsoft demo code exactly to be 100% sure. What seems to happen is the offset gets bigger the further away i start from the top left corner. A bit like there is a scaling factor being used somewhere but there isn't one in the code. I'm about to try on a different computer as i can only think its something to do with screen resolution or the way my laptop handles the screen, i know it shouldn't be but... Weird, i've had this code working for several years and nothing has changed to stop it working other than my laptop...
