Can't click buttons and sliders

[nige777]

I too have come across this problem when working on a particular machine - namely a widescreen (16:9) sony viao with windoze 7 and an ATI video card.??
If I attach a cross hair image to the mouse pos, it is positioned above the actual mouse pointer, also GUI buttons that are positioned towards the top of the screen are off the viewing area (with this machine) when they are visible on other machines, meaning I have to alter their pos for this machine only

Any Vizard Wizards have any idea why this might be?
