Sure you can do it all on the second box. I'm not sure what's wrong. To save time let me say three things at once.

1. You may have accidentally renamed some objects like folders, buttons, etc., on your desktop besides the WoW windows "wow1", "wow2", etc. I've noticed that people do that pretty often when they start out with HKN. The renamed objects may be invisible. If that's the case, then when you press F1, HKN will try to modify those things instead of the WoW windows. Your WoW windows -- when they are open -- should say wow1, wow2, etc. in the title bars on the tops of the windows.

2. I didn't understand what you meant when you said "Open wow 1-4. run HKN, swap back over to wow#". Did you mean you click on one of the WoW windows? That's not necessary. There's nothing in the sample that has anything to do with which window is active or in the foreground. And yet you say "the window I am in" behaves in a distinctive way. But the sample doesn't know which window you're in, so I'm guessing the sample got screwed up somehow. Which leads me to number 3.

3. Could you please post or email me the entire contents of your file?
