So can this be done? What I'm aiming for is a script step that positions a window relative to the *right* edge of the screen--a position which would vary depending on the size of monitor being used.

I know how to position and size from the left using either FM7's move/resize script or Apple Script's position or bounds. But those don't help if I want the window to always be positioned near the right edge, whether on a laptop screen or a large monitor.

Since the ScriptMaker move/resize dialogue allows for calculated results rather than fixed bounds, can somebody get me started with an If, or maybe a Case calculation that would start by measuring the available width of the screen?

You could use the Get ScreenWidth function minus the size of your window.

Thanks, that'll get me there! Hadn't ever noticed that function before. Time to print out the online function reference as an addendum to the User Guide....
