Mouse click by screen percentage.

Hi,

I was hoping someone could point me in the right direction. I am trying to automate some testing and whilst the majority of it can be done through key strokes there are sometimes that a mouse click is the only solution.

Could anyone tell me if there is a way to use percentages of the screen instead of coordinates (The testing will be run on different machines with varying screen resolutions / aspects), and also display the position of the mouse in a percentage of the screen.

If I am being completely stupid, please tell me also

Thanks

James
