Well, that's pretty bizarre. However, I'm not sure the culprit is "among", since on mouseUp local xyz put "1 2 3 4 " into xyz put ("penguin" is among the words of xyz) &CR&\ ("penguin" is among the items of "1, 2, 3, 4, ") end mouseUp returns false false ...maybe "penguin" is a subset of the set of empty words?... -- -Mark Wieder mwieder at ahsoftware.net
