Goofy button behavior

[Ken Norris]

Howdy,

I have a button which is not part of a group, and never was. It shows its
own selection handles, not group selection handles, with "Select Grouped
Controls" off, the same as other buttons which are not grouped. If I select
buttons which are grouped in that case, it shows the group's selection
handles. 

All OK so far? OK, now watch this (here's the problem):

It is executing the script of a group. In fact it is mixing the script of a
group to which it does not belong (in fact, it is not grouped at all) with
its own script.

What's going on and how do I fix it.
