[line eater fodder....]

I'm putting the finishing touches on a program than runs under 
Kickstart 2.0 and opens it's own screen.  Currently, the program lets
the user choose the screen mode to use (all screens are hires): 
interlaced, non-interlaced, productivity, and productivity-interlaced.
The following tags are used to define the screen type (the screen
is opened using OpenScreenTagList() ):  HIRES_KEY, HIRESLACE_KEY,
VGAPRODUCT_KEY, and VGAPRODUCTLACE_KEY.  

My question is, how can I be certain that if my program is run on
a PAL machine, that the PAL screen resolution will be used?  I've
tried using setting my Workbench screen to use PAL Hires-Interlaced,
but my program still comes up in NTSC.  I don't OR any of the MODE_KEYs
with a MONITOR_ID;  is there something else that needs to be done?  I've
included my program's NewScreen structure below for reference.

struct NewScreen NewScreen = {
   0,0,
   -1,-1,
   2,
   0,1,
   HIRES,  /*I've tried replacing this with NULL, but there's no change*/
   CUSTOMSCREEN,
   NULL,
   "'Liner V2.10b",
   NULL,
   NULL,
};

The only other tag I'm using is SA_PENS, BTW.

One other, unrelated question:  what's the difference between
A2024TENHERTZ_KEY and A2024FIFTEENHERTZ_KEY?  

Thanks in advance.
