I would like a panel to always be 80 above the bottom of the full screen or the window regardless of the screen resolution.

This doesn't work:

pos_y = (screen_size.y - 80);
or
pos_y = (screen_size.y)- 80;

And this doesn't work:

var desktopHeight;
desktopHeight = sys_metrics(1); (in the main function)

pos_y = (desktopHeight -80);
or
pos_y = (desktopHeight)-80;

Any suggestions would be appreciated. Thanks.
