I thought that was probably the case, but it's good to know for sure.

I was surprised that I couldn't find that fundamental bit of information in the help files or discussions.

I have another question. It's related but different. So I'll ask it separately, as a new post. ]]> RE: Index Number of Top Left Pixel on Main Monitor?

The values start at 0,0 yep!

You are correct as well, you would use the full resolution of your monitor at 1920x1080.

Thanks! ]]> Index Number of Top Left Pixel on Main Monitor?

Is it 0,0? Or is it 1,1?

Secondly, I presume that, even if "Position X" and "Position Y" are 0 (rather than 1), this does not affect the height and width measurements? For example, if I wanted the function to expand a window to use the full area of a monitor (which had a resolution of 1920 x 1200), then the height and width parameters would be 1920 and 1200 (not 1919 and 1199).

Thanks. ]]>
