Excellent point. And this happens quite a bit with beginning
students. How easy is it to inadvertently alt/option-drag an object?
Or Command/Control-C then Command/Control-V,V? (Oops! didn't realize
I hit paste twice!)
Another naming gotcha: Have you ever gotten an "object doesn't
exist" error, and you check the name and it looks exactly right and
you spend a long time trying to figure out why your handler can't
see it? This happened to me years ago in HyperCard, and I spent many
hair-pulling-out minutes trying to figure it out. I finally
discovered that I had put a space at the end of the button name in
the button inspector dialog. I deleted it and, presto! Button now
exists! Nowadays that's one of the first things I check in
situations like this.
How about when you have two objects with identical names, such as
when you inadvertently copy the object twice. You edit the script of
the visible object, but if a handler sends a message other than
mouseUp to the script of object "someName", it may go to the other
object, and you wonder why your newly changed script didn't work.
Duplications are so easy to do. And if you have a lot of objects,
you might not notice the two identical objects if you pull up the
list of objects and the two are miles apart in the listing.
