A Positioning Mystery

[Rob Cozens]

>The rect (and therefore the loc) of a group changes every time the

>that of any other group control is changed.

Eureka!

If I ...

	lock screen
	show [a control whose rect encompasses all other controls in the group]
	set the loc of [the group]
	hide [a control whose rect encompasses all other controls in the group]
	[rest of resize statements]
	unlock screen

all is well.

However, I'm pretty sure the animation played a part too, as the 
animated image (after animation) has the same rect as the button 
shown & hidden above; so I'm classifying this as a double mystery:

1. The animation caused a change in the position of the animated 
image relative to the other controls in the same group.

2. When the animated image was removed from the group, the second bug bit.

...solved [or explained: I see the workaround and group locs changing 
with control visibility changes as "Mickey Mouse"] with a little help 
from my friends.   :{`)
