I guess HC2.0's "there is" doesn't have the ability to check if 
there's an object at a certain point. The manual doesn't cover
"there is" very well. I think it's only mentioned in a table of
functions (or commands? properties?) I tried "If there is a bg 
btn at 442,42 then beep". I got an error message.

Is there another way around this? I'd like to look at a specific 
location and see if there's a button there without looking at
every button and comparing its loc with the desired loc.

I know if there's a cool way to do this I'll find it here.

Thanks,
	ken
