Group Edit anomaly

[Graham Samuel]

I've got a card which contains various graphics, images and groups. Two of 
the images are used in a simple animation of sliding doors (one left, one 
right): I simply have a loop which reduces the width of each door 
progressively while keeping them anchored to the door frame, with a small 
delay between iterations. Works fine, but I have the following problem.

I need to open a group on the card for editing (via script - although the 
behaviour I'm describing happens in the IDE too). If my 'doors' are in the 
'open' position (i.e. they have had their widths reduced to about one tenth 
of the original width), the act of opening the (unrelated) group for 
editing and closing it again has an effect on the door images! They return 
to their original width and are spaced further apart than they were. I 
cannot imagine what's doing this, but I have got it down to a completely 
repeatable sequence. For a start, where can the memory of the original door 
width be kept? Of course it can be my error, but I can't see what sort of 
error it could be. I'm not running any script in the group or any of its 
components, nor in the door images.

I'm looking for a workaround, but meanwhile can anyone suggest what's 
happening?

TIA

Graham
