Is this a bug?

[David Bovill]

Yes I agree it is not a bug in terms of naming - it would be perhaps be more
natural if the "exists" function makes an exception here as clearly the
object does exist. I use long ids every where and put them in a varaible:

put the long id of group 1 into firstAmerican
put the long id of group 2 into newRepublican

put exists(button "taxes" of firstAmerican)
put exists(button "UFOs" of newRepublican)
