I've been using MeasureTool Version 4 with Mac OS 10.3.5.  When Roy (I think it was) 
mentioned that PM 5.x has a MeasureTool that works with Tiger, I downloaded the newer 
version.  However, with Version 5, Spot Measurement is grayed out, although the Spot 
Measurement function works fine on Version 4.  Does anyone have any thoughts on why 
that might be?
