HyperCard 1.x will always return the coordinates of the main screen when 
the screenRect function is called. HyperCard 2.0 returns the rect of the 
screen where the card window lies (or in overlapping situations, the one 
containing the largest area of the card window). This obviously only 
happens on machines with multiple monitors.

You can use this to check if you're on the main screen or not (item 1 to 2 
of the screenRect is only "0,0" on the main monitor). Note that the 
coordinates returned can be negative for when the screen is to the left 
and/or above the main screen. If you're not on the main screen you don't 
need to account for the 20-pixel menuBar (more under script systems, e.g. 
KanjiTalk).
